CVSS score: 10 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H)
CWE: CWE-77
Description: A flaw was found in webkitgtk in versions prior to 2.28.3 and in WPE WebKit in versions prior to 2.28.3. The bubblewrap sandbox failed to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg- desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal’s input buffer, similar to CVE-2017-5226. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25661 (Important severity, published 2020-11-02)
CVSS score: 8.8 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CWE: CWE-843
Description: A Red Hat only CVE-2020-12351 regression issue was found in the way the Linux kernel's Bluetooth implementation handled L2CAP packets with A2MP CID. This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or potentially executing arbitrary code on the system by sending a specially crafted L2CAP packet. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
Statement: This issue only affects the Linux kernel version as shipped with the Red Hat Enterprise Linux 8.3 GA release, kernel-4.18.0-240.el8 (and any kernel derived from this release such as kernel rt-4.18.0-240.rt7.54.el8). Red Hat was unable to include the fix for the original CVE-2020-12351 issue in the GA release, as the Red Hat Enterprise Linux 8.3 GA release was in its final stages of release preparation when CVE-2020-12351 was made public. All of the subsequent Red Hat Enterprise Linux 8 kernel versions, including the version included in the so-called 0day (released on the same day or very close to that day) erratum, contain the fix, thus immune to the original CVE-2020-12351 issue.
Mitigation: To mitigate these vulnerabilities on the operating system level, disable the Bluetooth functionality via blocklisting kernel modules in the Linux kernel. The kernel modules can be prevented from being loaded by using system-wide modprobe rules. Instructions on how to disable Bluetooth modules are available on the Customer Portal at https://access.redhat.com/solutions/2682931.

Alternatively, Bluetooth can be disabled within the hardware or at BIOS level which will also provide an effective mitigation as the kernel will not be able to detect that Bluetooth hardware is present on the system.

CVSS score: 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H)
Description: An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service or possibly gain privileges because of missing memory barriers in read-write unlock paths. The read-write unlock paths don't contain a memory barrier. On Arm, this means a processor is allowed to re-order the memory access with the preceding ones. In other words, the unlock may be seen by another processor before all the memory accesses within the "critical" section. As a consequence, it may be possible to have a writer executing a critical section at the same time as readers or another writer. In other words, many of the assumptions (e.g., a variable cannot be modified after a check) in the critical sections are not safe anymore. The read-write locks are used in hypercalls (such as grant-table ones), so a malicious guest could exploit the race. For instance, there is a small window where Xen can leak memory if XENMAPSPACE_grant_table is used concurrently. A malicious guest may be able to leak memory, or cause a hypervisor crash resulting in a Denial of Service (DoS). Information leak and privilege escalation cannot be excluded.

CVSS score: 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
CWE: CWE-347
Description: A flaw was found in the way the perl-CPAN performed verification of package signatures stored in CHECKSUMS files. A malicious or compromised CPAN server used by a user, or a man-in-the-middle attacker, could use this flaw to bypass signature verification.
Statement: This vulnerability was rated as MODERATE severity because it allows an attacker to inject malicious packages into the CPAN system by bypassing signature verification, it requires the attacker to control a CPAN mirror and deceive the victim into using it, it poses a risk of installing compromised software.

Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-347: Improper Verification of Cryptographic Signature vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.

The platform uses secure, encrypted HTTPS connections over TLS 1.2, and access to all platform resources is restricted by default. Red Hat enforces strong authentication through hard token-based multi-factor authentication (MFA), combined with least privilege principles to ensure that only authorized users and roles can execute or modify code. Internal and external certificates are established and maintained within a secure environment, and the platform enforces the use of FIPS-validated cryptographic modules across all compute resources. This reduces the risk of improper cryptographic signatures by ensuring that keys used for signature generation and verification are created with approved algorithms, securely managed, and protected against unauthorized access. Additionally, static code analysis and peer code reviews support robust input validation and error handling, reducing the likelihood of missing or improperly implemented signature validation mechanisms.
Mitigation: This issue can be mitigated by configuring perl-CPAN to only use trusted CPAN mirrors (www.cpan.org or cpan.metacpan.org) and use HTTPS for communication with CPAN servers.  If you already have a cpan configured, the list of configured mirrors can be viewed by running the `cpan` command without any argument and entering the following command on the cpan command's prompt:

```
  o conf urllist
```

Ensure that the URL list only includes trusted mirrors and that https:// scheme is used for all URLs.  A different set of mirrors can be configured using the following commands (these examples show how to configure one or more mirrors, only one of the commands should be used):

```
  o conf urllist https://www.cpan.org
  o conf urllist https://www.cpan.org https://cpan.metacpan.org
```

After changing configuration, the following command must be used to save the configuration:

```
  o conf commit
```
