CVE-2020-12413 (Low severity, published 2020-09-08)
CVSS score: 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CWE: CWE-200
Description: A flaw was found in Mozilla nss. A raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman(DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The highest threat from this vulnerability is to data confidentiality.
Statement: NSS as shipped with Red Hat Enterprise Linux 6, 7, and 8 does not re-use Diffie-Hellman Ephemeral (DHE) keys. It reuses Elliptic Curve Diffie-Hellman Ephemeral (ECDHE) keys by default, but Attacking ECDH and ECDHE cipher suites are not in the scope of the Raccoon Attack and generally considered to be unaffected [1]. Further, reuse of ECDHE keys can be disabled starting in nss 3.17 [2].

For these reasons, Red Hat Product Security has marked the Severity of this flaw as Low. Please see [3] for more information about Low Severity ratings.

Mitigation: Any risk involving the ECDHE key reuse on the nss server can be mitigated by setting the SSL_REUSE_SERVER_ECDHE_KEY socket option to PR_FALSE.
CVE-2020-28502 (Important severity, published 2021-03-04)
CVSS score: 8.1 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-20
Description: An arbitrary code injection vulnerability was found in nodejs-xmlhttprequest. For this vulnerability to occur, the connection must be initialized during the function call XMLHttpRequest.open to send requests synchronously using the parameter `async=False`. If the subsequent calls to xhr.send functions are with user-controllable input, this flaw allows an attacker to execute arbitrary code. If the xhr.send function is called on the server on behalf of a user, this allows execution on the Node.js server using the privileges of the Node.js process. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
Statement: While the OpenShift ServiceMesh (OSSM) grafana-container source does have a vulnerable version of the nodejs-xmlhttprequest, it does not bundle or use the library in the released product. Therefore, the container has been marked `not affected`.

For the OpenShift Container Platform (OCP), the grafana-container for OCP 4.5 is already using a non-affected version of xmlhttprequest (v1.8.0). Later versions of the container (4.6+) don't include xmlhttprequest.

For Red Hat Advanced Cluster Management for Kubernetes (RHACM), the different components using xmlhttprequest is already using a non-affected version (v1.8.0). Therefore, all supported RHACM versions have been marked `not affected`.

For Red Hat Ceph Storage (RHCS) 3 and 4 the grafana-container is already using a non-affected version of xmlhttprequest (v1.8.0).

CWE: CWE-129
Description: A flaw was found in golang.org. In x/text, an "index out of range" panic occurs in language.ParseAcceptLanguage while parsing the -u- extension.
Statement: Below Red Hat products include the affected version of 'golang.org/x/text', however the language package is not being used and hence they are rated as having a security impact of Low. A future update may address this issue.

* Red Hat OpenShift Container Storage 4
* OpenShift ServiceMesh (OSSM)
* Red Hat Gluster Storage 3
* Windows Container Support for Red Hat OpenShift

Only three components in OpenShift Container Platform include the affected package, 'golang.org/x/text/language' , the installer, baremetal installer and thanos container images. All other components that include a version of 'golang.org/x/text' do not include the 'language' package and are therefore not affected.
CVE-2020-16000 (Important severity, published 2020-10-19)

Description: In BIND 9.15.6 -> 9.16.5, 9.17.0 -> 9.17.3, An attacker who can establish a TCP connection with the server and send data on that connection can exploit this to trigger the assertion failure, causing the server to exit.
Statement: This version only affects bind-9.16.x. Therefore versions of bind package shipped with Red Hat Enterprise Linux are not affected by this flaw.
CVE-2020-16846 (Important severity, published 2020-11-02)
CVSS score: 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-78
Description: A flaw was found in salt. A shell injection vulnerability was found where an unauthenticated user with network access to the Salt API can use shell injections to run code on the Salt-API using the SSH client. An attacker could use this flaw to cause a denial of service, information disclosure, or privilege escalation. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement: Red Hat Ceph Storage 2 shipped salt for the usage of Red Hat Storage Console 2 (RHSCON-2), which required salt to administrate ceph nodes. RHSCON-2 has reached End Of Life, hence salt is no longer used and supported. Therefore, the salt package provided by Red Hat Ceph Storage 2 has been marked as 'will not fix'.
Mitigation: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update as soon as possible.
CVE-2020-25625 (Low severity, published 2020-09-10)
CVSS score: 2.5 (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:L)
CWE: CWE-835
Description: An infinite loop flaw was found in the USB OHCI controller emulator of QEMU. This flaw occurs while servicing OHCI isochronous transfer descriptors (TD) in the ohci_service_iso_td routine, as it retires a TD if it has passed its time frame. It does not check if the TD was already processed and holds an error code in TD_CC. This issue may happen if the TD list has a loop. This flaw allows a guest user or process to consume CPU cycles on the host, resulting in a denial of service.
CVE-2020-27618 (Low severity, published 2020-07-08)
CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-835
Description: A flaw was found in glibc. If an attacker provides the iconv function with invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, IBM1399 encodings, it fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service.
Statement: Red Hat Product Security has rated this flaw as a "Low" severity rating because the affected encodings are uncommon, and an attacker would need to either have local privileges or depend on an application feeding untrusted encoding input to iconv. Low and Moderate severity flaws are out of support scope for glibc as shipped with:

* Red Hat Enterprise Linux 5
* Red Hat Enterprise Linux 6
* Red Hat Enterprise Linux 7

CVE-2020-6794 (Moderate severity, published 2020-02-10)
CVSS score: 6.1 (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
CWE: CWE-312
Description: If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Thunderbird < 68.5.
CVE-2020-25275 (Low severity, published 2021-01-03)
CVSS score: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-20
Description: Dovecot before 2.3.13 has Improper Input Validation in lda, lmtp, and imap, leading to an application crash via a crafted email message with certain choices for ten thousand MIME parts.

Description: When protecting CSS blocks with the nonce feature of Content Security Policy, the @import statement in the CSS block could allow an attacker to inject arbitrary styles, bypassing the intent of the Content Security Policy. This vulnerability affects Firefox < 74.
CVE-2020-27835 (Moderate severity, published 2020-11-24)
CVSS score: 6.4 (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-416
Description: A flaw use after free in the Linux kernel infiniband hfi1 driver was found in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system.
Statement: This flaw is rated as having a Moderate impact because the issue can only be triggered by an authorized local user with access to a system with specific hardware present.
Mitigation: To mitigate this issue, prevent the module hfi1 from being loaded. Please see https://access.redhat.com/solutions/41278 for information on how to denylist a kernel module to prevent it from loading automatically.
CVE-2020-14656 (Moderate severity, published 2020-07-13)
CVSS score: 4.9 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H)
Description: Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Locking). Supported versions that are affected are 8.0.20 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).
CVE-2020-14343 (Moderate severity, published 2020-07-21)
CVSS score: 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-20
Description: A vulnerability was discovered in the PyYAML library, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. This flaw allows an attacker to execute arbitrary code on the system by abusing the python/object/new constructor. This flaw is due to an incomplete fix for CVE-2020-1747.
Statement: This CVE has already been fixed in RHEL-9 with initial release of PyYaml v5.4-1.

Ansible Tower 3.7 uses affected version of PyYAML 3.12 from RHEL, but the use of load() is specified with a SafeLoader when it is called. So Ansible Tower and Ansible Engine are not affected.

Red Hat Quay, from version 3.4 uses the safe_load function which is not affected by this issue. See [1].

Even though the CVSSv3 for this flaw is 9.8, the Impact has been set to Moderate because PyYAML provides a specific method to deal with untrusted input, which is `yaml.safe_load`. `yaml.safe_load` or the SafeLoader loader should be used whenever the input YAML can be modified by a malicious user.

[1] https://github.com/quay/quay/pull/603
Mitigation: Use `yaml.safe_load` or the SafeLoader loader when you parse untrusted input.

Description: An out-of-bounds read vulnerability was found in the SQLite component of the Chromium browser. A remote attacker could abuse this flaw to obtain potentially sensitive information from process memory via a crafted HTML page. The highest threat from this vulnerability is to data confidentiality.
Statement: This flaw did not affect the versions of SQLite as shipped with Red Hat Enterprise Linux 5, 6 and 7 as they did not include the WHERE-clause constant propagation optimization, which was introduced in a later version of the package.
CVE-2020-10750 (Moderate severity, published 2020-06-19)

CVE-2020-10029 (Moderate severity, published 2020-02-11)
CVSS score: 5.7 (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H)
CWE: CWE-121
Description: A flaw was found in glibc in versions prior to 2.32. Pseudo-zero values are not validated causing a stack corruption due to a stack-based overflow. The highest threat from this vulnerability is to system availability.
Statement: The glibc version shipped with Red Hat Enterprise Linux 8 is compiled using gcc's stack-protector option which mitigates the possibility of code execution led by the stack corruption.

The glibc version shipped with Red Hat Enterprise Linux 7 is more difficult to exploit using this flaw, specifically for remote code execution. Because exploitation of the flaw depends on the usage of pseudo-zero values, an attacker can only overwrite the stack with 0s. Due to this, a valid address value for code execution is difficult to get and is likely to only result in a crash.

CWE: CWE-502
Description: A flaw was found in jackson-databind. FasterXML mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement: The following Red Hat products do ship the vulnerable component, but do not enable the unsafe conditions needed to exploit, lowering their vulnerability impact:
* JBoss Data Grid 7
* Business Process Management Suite 6
* Business Rules Management Suite 6
* JBoss Data Virtualization 6
* Red Hat Fuse Service Works 6
* Red Hat OpenStack Platform
* Red Hat OpenShift containers: ose-metering-hadoop, ose-metering-hive, ose-logging-elasticsearch5, ose-logging-elasticsearch6  
These products may update the jackson-databind dependency in a future release.

In Red Hat Openshift 4 there are no plans to maintain the ose-logging-elasticsearch5 container, therefore it has been marked wontfix at this time and may be fixed in a future update. 

The following Red Hat products ship OpenDaylight, which contains the vulnerable jackson-databind, but do not expose jackson-databind in a way that would make it exploitable:
* Red Hat OpenStack Platform 13
As such, Red Hat will not be providing a fix for OpenDaylight at this time.

The following Red Hat products are not affected by this flaw because they use a more recent version of jackson-databind that does not contain the vulnerable code:
* CodeReady Studio 12.16.0
* Red Hat Enterprise Linux 8
* Red Hat Enterprise Virtualization
* Red Hat Satellite 6
* Red Hat OpenShift container: ose-metering-presto
Mitigation: The following conditions are needed for an exploit, we recommend avoiding all if possible:
* Deserialization from sources you do not control
* `enableDefaultTyping()`
* `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS`
* avoid: oadd.org.apache.commons.dbcp.cpdsadapter.DriverAdapterCPDS, org.apache.commons.dbcp2.cpdsadapter.DriverAdapterCPDS, org.apache.tomcat.dbcp.dbcp.cpdsadapter.DriverAdapterCPDS, org.apache.tomcat.dbcp.dbcp2.cpdsadapter.DriverAdapterCPDS, org.docx4j.org.apache.xalan.lib.sql.JNDIConnectionPool, org.apache.tomcat.dbcp.dbcp2.datasources.PerUserPoolDataSource, org.apache.tomcat.dbcp.dbcp2.datasources.SharedPoolDataSource, org.apache.tomcat.dbcp.dbcp.datasources.PerUserPoolDataSource, org.apache.tomcat.dbcp.dbcp.datasources.SharedPoolDataSource, com.newrelic.agent.deps.ch.qos.logback.core.db.JNDIConnectionSource, com.newrelic.agent.deps.ch.qos.logback.core.db.DriverManagerConnectionSource

CVSS score: 0 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N)
CWE: CWE-345
Description: For some of the Postfix configurations, the remote user can send e-mails pretending to be someone else (or even using non-existing user name with some homoglyph characters). One of the discussed problems that Postfix params "smtpd_sender_login_maps" and "smtpd_sender_restrictions" looks useless because works only for authorized users and attacker could get round with anonymous sending e-mails to any local user. The described issue should not be considered as security issue, so it is "DISPUTED".
Statement: Red Hat Product Security does not consider this to be a vulnerability. The described problem is problem of possibly incorrect Postfix configuration, but not bug of Postfix itself. Both no way to totally resolve the described in CVE problem, because it is how SMTP protocol designed. Means that SMTP protocol allows some SPAM or forging e-mails and no way to prevent it totally, but if configuring Postfix well, then possible to make it more strict (less SPAM and less forging).
Mitigation: The described problem could be prevented with the usage of the postfix configuration param check_sender_access (part of smtpd_sender_restrictions) for domain names being used for receiving e-mails with param reject_unverified_sender for each of these domains.

The related part of postfix configuration example:

smtpd_sender_login_maps = texthash:/etc/postfix/sender_login
smtpd_sender_restrictions =
    check_sender_access texthash:/etc/postfix/sender_access
    reject_sender_login_mismatch
    reject_unknown_sender_domain

and the content of the file /etc/postfix/sender_access would be:

mail.mydomain.com reject_unverified_sender

and the content of the file /etc/postfix/sender_login would be:

username@mail.mydomain.com username@mail.mydomain.com
