Red Hat Security Advisory 2023-2097-03 - Red Hat Satellite is a systems management tool for Linux-based infrastructure. It allows for provisioning, remote management, and monitoring of multiple Linux deployments with a single centralized tool. Issues addressed include code execution, cross site scripting, denial of service, deserialization, improper neutralization, information leakage, and remote shell upload vulnerabilities.

Debian Linux Security Advisory 5397-1 - Vulnerabilities have been discovered in the WebKitGTK web engine. Luan Herrera discovered that an HTML document may be able to render iframes with sensitive user information. P1umer and Q1IQ discovered that processing maliciously crafted web content may lead to arbitrary code execution. An anonymous researcher discovered that processing maliciously crafted web content may bypass Same Origin Policy. An anonymous researcher discovered that a website may be able to track sensitive user information. Clement Lecigne and Donncha O Cearbhaill discovered that processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.

Debian Linux Security Advisory 5396-1 - Vulnerabilities have been discovered in the WebKitGTK web engine.

An issue was discovered in bgpd in FRRouting (FRR) through 8.4. By crafting a BGP OPEN message with an option of type 0xff (Extended Length from RFC 9072), attackers may cause a denial of service (assertion failure and daemon restart, or out-of-bounds read). This is possible because of inconsistent boundary checks that do not account for reading 3 bytes (instead of 2) in this 0xff case.

Debian Linux Security Advisory 5395-1 - An untrusted search path vulnerability was discovered in Node.js, which could result in unexpected searching or loading ICU data when running with elevated privileges.

Debian Linux Security Advisory 5394-1 - Several vulnerabilities have been discovered in the FFmpeg multimedia framework, which could result in denial of service or potentially the execution of arbitrary code if malformed files/streams are processed.

Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege.

Apptainer is an open source container platform for Linux. There is an ext4 use-after-free flaw that is exploitable through versions of Apptainer < 1.1.0, installations that include apptainer-suid < 1.1.8, and all versions of Singularity in their default configurations on older operating systems where that CVE has not been patched. That includes Red Hat Enterprise Linux 7, Debian 10 buster (unless the linux-5.10 package is installed), Ubuntu 18.04 bionic and Ubuntu 20.04 focal. Use-after-free flaws in the kernel can be used to attack the kernel for denial of service and potentially for privilege escalation. Apptainer 1.1.8 includes a patch that by default disables mounting of extfs filesystem types in setuid-root mode, while continuing to allow mounting of extfs filesystems in non-setuid "rootless" mode using fuse2fs. Some workarounds are possible. Either do not install apptainer-suid (for versions 1.1.0 through 1.1.7) or set `allow setuid = no` in apptainer.conf (or singularity.conf ...

### Impact There is an ext4 use-after-free flaw described in CVE-2022-1184 that is exploitable through versions of Apptainer < 1.1.0, installations that include apptainer-suid < 1.1.8, and all versions of Singularity in their default configurations on older operating systems where that CVE has not been patched. That includes Red Hat Enterprise Linux 7, Debian 10 buster (unless the linux-5.10 package is installed), Ubuntu 18.04 bionic and Ubuntu 20.04 focal. Use-after-free flaws in the kernel can be used to attack the kernel for denial of service and potentially for privilege escalation. ### Background Historically there have been many CVEs published for extfs and a smaller number for squashfs, including serious use-after-free and buffer overrun vulnerabilities, that are scored as "Moderate" or "Low" impact only because unprivileged users were assumed to not have write access to the raw data. Because of those ratings, vendors treat such CVEs as low urgency and either delay a patch u...

Debian Linux Security Advisory 5393-1 - Multiple security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.
