CVSS score: 5.6 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:H)
CWE: CWE-667
Description: In the Linux kernel, the following vulnerability has been resolved:

net: systemport: Add global locking for descriptor lifecycle

The descriptor list is a shared resource across all of the transmit queues, and
the locking mechanism used today only protects concurrency across a given
transmit queue between the transmit and reclaiming. This creates an opportunity
for the SYSTEMPORT hardware to work on corrupted descriptors if we have
multiple producers at once which is the case when using multiple transmit
queues.

This was particularly noticeable when using multiple flows/transmit queues and
it showed up in interesting ways in that UDP packets would get a correct UDP
header checksum being calculated over an incorrect packet length. Similarly TCP
packets would get an equally correct checksum computed by the hardware over an
incorrect packet length.

The SYSTEMPORT hardware maintains an internal descriptor list that it re-arranges
when the driver produces a new descriptor anytime it writes to the
WRITE_PORT_{HI,LO} registers, there is however some delay in the hardware to
re-organize its descriptors and it is possible that concurrent TX queues
eventually break this internal allocation scheme to the point where the
length/status part of the descriptor gets used for an incorrect data buffer.

The fix is to impose a global serialization for all TX queues in the short
section where we are writing to the WRITE_PORT_{HI,LO} registers which solves
the corruption even with multiple concurrent TX queues being used.

CWE: CWE-20
Description: In the Linux kernel, the following vulnerability has been resolved:

KVM: VMX: Always clear vmx->fail on emulation_required

Revert a relatively recent change that set vmx->fail if the vCPU is in L2
and emulation_required is true, as that behavior is completely bogus.
Setting vmx->fail and synthesizing a VM-Exit is contradictory and wrong:

  (a) it's impossible to have both a VM-Fail and VM-Exit
  (b) vmcs.EXIT_REASON is not modified on VM-Fail
  (c) emulation_required refers to guest state and guest state checks are
      always VM-Exits, not VM-Fails.

For KVM specifically, emulation_required is handled before nested exits
in __vmx_handle_exit(), thus setting vmx->fail has no immediate effect,
i.e. KVM calls into handle_invalid_guest_state() and vmx->fail is ignored.
Setting vmx->fail can ultimately result in a WARN in nested_vmx_vmexit()
firing when tearing down the VM as KVM never expects vmx->fail to be set
when L2 is active, KVM always reflects those errors into L1.

CWE: CWE-125
Description: A vulnerability was found in the Linux kernel whereby hardware registries that have the server TID base may contain invalid values when the adapter is in a bad state. Reading these invalid values can result in out-of-bounds memory access, which can cause memory corruption or crashes.
Statement: Red Hat believes this vulnerability to be of Moderate impact because the privileges required for exploitation are high. More specifically, privileged code is required to intentionally place the adapter into a bad state and then trigger the cxgb4 filter cleanup routines.
CVE-2021-45105 (Moderate severity, published 2021-12-17)
CVSS score: 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-674
Description: A flaw was found in the Apache Log4j logging library 2.x. when the logging configuration uses a non-default Pattern Layout with a Context Lookup. Attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup and can cause Denial of Service.
Statement: Red Hat Product Security has performed an analysis of this flaw and has classified the Attack Complexity(AC) as High because there are multiple factors involved which are beyond attacker's control:

- The application has to use the logging configuration using a Context Map Lookup (for example, $${ctx:loginId}) which is a non-default Pattern Layout.
- The application developer has to use the map org.apache.logging.log4j.ThreadContext in the application code and save at-least one key (for example, ThreadContext.put("loginId", "myId");) in the ThreadContext map object.
- Attackers must also know this saved key name in order to exploit this flaw.

Note that saving keys in this map is a non-essential usage of log4j and just an optional feature provided. Refer to https://logging.apache.org/log4j/2.x/manual/lookups.html#ContextMapLookup to know more about the Context Map Lookup feature of Log4j.

Log4j 1.x is not impacted by this vulnerability. Note that only the log4j-core JAR file is impacted by this vulnerability. Applications using ONLY the log4j-api JAR file without the log4j-core JAR file are NOT impacted by this vulnerability.


Despite including a vulnerable version of Log4j 2.x, this vulnerability is not exploitable in Elasticsearch[0], as shipped in OpenShift Container Platform and OpenShift Logging. OpenShift 3.11 specifically does not contain any context lookups:

https://github.com/openshift/openshift-ansible/blob/release-3.11/roles/openshift_logging_elasticsearch/templates/log4j2.properties.j2

This vulnerability is therefore rated Low for Elasticsearch in OpenShift Container Platform and OpenShift Logging.

Mitigation: For Log4j 2 versions up to and including 2.16.0, this flaw can be mitigated by:
- In PatternLayout in the Log4j logging configuration, replace Context Lookups like ${ctx:loginId} or $${ctx:loginId} with Thread Context Map patterns (%X, %mdc, or %MDC) like %X{loginId}.
- Otherwise, in the Log4j logging configuration, remove references to Context Lookups like ${ctx:loginId} or $${ctx:loginId} where they originate from sources external to the application such as HTTP headers or user input.

CWE: CWE-22
Description: A path traversal and remote code execution flaw was found in Apache HTTP Server 2.4.49 and 2.4.50. A remote attacker could use this flaw to map URLs to files outside the expected document root. Additionally, this flaw could leak the source of interpreted files like CGI scripts. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased paths, this could allow for remote code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. This is an incomplete fix for CVE-2021-41773.
Statement: This issue only affects httpd 2.4.49 and 2.4.50, earlier versions are not affected. Therefore this issue does not affect the versions of httpd shipped with Red Hat products.

CWE: CWE-20
Description: In the Linux kernel, the following vulnerability has been resolved:

ACPI: GTDT: Don't corrupt interrupt mappings on watchdow probe failure

When failing the driver probe because of invalid firmware properties,
the GTDT driver unmaps the interrupt that it mapped earlier.

However, it never checks whether the mapping of the interrupt actially
succeeded. Even more, should the firmware report an illegal interrupt
number that overlaps with the GIC SGI range, this can result in an
IPI being unmapped, and subsequent fireworks (as reported by Dann
Frazier).

Rework the driver to have a slightly saner behaviour and actually
check whether the interrupt has been mapped before unmapping things.

CWE: CWE-125
Description: A flaw was found in the hivex library. It is caused due to a lack of bounds check within the hivex_open function. An attacker could input a specially crafted Windows Registry (hive) file which would cause hivex to read memory beyond its normal bounds or cause the program to crash. The highest threat from this vulnerability is to system availability.
Statement: The hivex utility being non-privileged, does not handle any confidential information. Any external program using the hivex library could be exposed to partial unavailability in case of a crash where a user can always retry the operation. As for libguestfs, a crash in hivex would not result in libguestfs crashing.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

CWE: CWE-79
Description: An improper neutralization of input vulnerability was found in datatables.net. If an array is passed to the HTML escape entities function, it does not have its contents escaped, possibly leading to cross site scripting (XSS).
Statement: The improper neutralization of input vulnerability in DataTables.net is considered a moderate severity issue because, while it allows for potential cross-site scripting (XSS) attacks, it requires specific conditions to be exploited effectively. An attacker must have the ability to inject malicious input into the system, and the application must pass this input to the HTML escape entities function without proper validation. Although XSS can lead to significant security risks, such as session hijacking and data theft, the impact is somewhat mitigated by the necessity of these preconditions. Moreover, this vulnerability does not compromise the underlying server or database directly, limiting its scope primarily to client-side exploitation.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

CWE: CWE-459
Description: A flaw was found in Apache Tomcat. This flaw allows an attacker to remotely trigger a denial of service. An error introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag associated with the Request object was not reset between requests. This means that once a non-blocking I/O error occurred, all future requests handled by that request object would fail. Users can trigger non-blocking I/O errors (ex. by dropping a connection), creating the possibility of triggering a denial of service. Applications that do not use non-blocking I/O are not exposed to this vulnerability. The highest threat from this vulnerability is to system availability.
Statement: Red Hat OpenStack Platform's OpenDaylight will not be updated for this flaw because it was deprecated as of OpenStack Platform 14 and is only receiving security fixes for Critical flaws.
