lxc-user-nic in lxc through 5.0.1 is installed setuid root, and may allow local users to infer whether any file exists, even within a protected directory tree, because "Failed to open" often indicates that a file does not exist, whereas "does not refer to a network namespace path" often indicates that a file exists. NOTE: this is different from CVE-2018-6556 because the CVE-2018-6556 fix design was based on the premise that "we will report back to the user that the open() failed but the user has no way of knowing why it failed"; however, in many realistic cases, there are no plausible reasons for failing except that the file does not exist.

NVIDIA GPU Display Driver for Windows contains a vulnerability where a regular user can cause an out-of-bounds read, which may lead to code execution, denial of service, escalation of privileges, information disclosure, or data tampering.

NVIDIA distributions of Linux contain a vulnerability in nvdla_emu_task_submit, where unvalidated input may allow a local attacker to cause stack-based buffer overflow in kernel code, which may lead to escalation of privileges, compromised integrity and confidentiality, and denial of service.

Hello everyone! Great news for my open source Scanvus project! You can now perform vulnerability checks on Linux hosts and docker images not only using the Vulners.com API, but also with the Vulns.io VM API. It’s especially nice that all the code to support the new API was written and contributed by colleagues from Vulns.io. […]

Gentoo Linux Security Advisory 202212-6 - Multiple vulnerabilities have been found in OpenSSH, the worst of which could result in arbitrary code execution. Versions less than 9.1_p1 are affected.

Gentoo Linux Security Advisory 202212-7 - An integer overflow vulnerability has been found in libksba which could result in remote code execution. Versions less than 1.6.3 are affected.

### Impact It is possible to craft an environment variable with newlines to add entries to a container's /etc/passwd. It is possible to circumvent admission validation of username/UID by adding such an entry. Note: because the pod author is in control of the container's /etc/passwd, this is not considered a new risk factor. However, this advisory is being opened for transparency and as a way of tracking fixes. ### Patches 1.26.0 will have the fix. More patches will be posted as they're available. ### Workarounds Additional security controls like SELinux should prevent any damage a container is able to do with root on the host. Using SELinux is recommended because this class of attack is already possible by manually editing the container's /etc/passwd ### References

ISOS firmwares from versions 1.81 to 2.00 contain hardcoded credentials from embedded StreamX installer that integrators are not forced to change.

StreamX applications from versions 6.02.01 to 6.04.34 are affected by a logic bug that allows to bypass the implemented authentication scheme. StreamX applications using StreamView HTML component with the public web server feature activated are affected.

Debian Linux Security Advisory 5306-1 - Several vulnerabilities were discovered in gerbv, a Gerber file viewer, which could result in the execution of arbitrary code, denial of service or information disclosure if a specially crafted file is processed.
