Ubuntu Linux has recently released multiple security updates addressing vulnerabilities in Samba, the Linux kernel, and Sudo. These updates include fixes for a Samba regression, several kernel vulnerabilities across multiple architectures, and issues in Sudo that could lead to privilege escalation.

Debian GNU/Linux has recently received multiple updates that enhance security across various packages, including critical components like Sudo, gst-plugins-good1.0, RAR, Catdoc, Commons-Vfs, and mbedtls. The updates are part of the Extended Long Term Support (LTS) for Debian versions 8 (Jessie), 9 (Stretch), and 10 (Buster), as well as the current LTS for Debian 11 (Bullseye) and the latest release, Debian 12 (Bookworm).

The Extended Long Term Support (ELTS) Team has announced the official end of support for Debian GNU/Linux 8, also known as "Jessie," effective June 30, 2025. This conclusion marks a full decade since the initial release of Jessie on April 26, 2015. Users are strongly encouraged to upgrade to a currently supported version of Debian to ensure they continue receiving security updates and support.

Red Hat Enterprise Linux (RHEL) has released several important security updates affecting various components such as the kernel, glibc, Python 3.11, Apache Kafka, Red Hat Service Interconnect, and the mod_auth_openidc modules.

The Slackware Linux team has released updated `sudo` packages for Slackware 15.0 and the -current version to address critical security vulnerabilities. The updates include version 1.9.17p1, which resolves issues that could potentially allow local privilege escalation attacks through the use of the `-h` (host) and `-R` (chroot) options in `sudo`. Specifically, if the sudoers file permits a user to execute commands on a different host, it could lead to unauthorized command execution as root, even bypassing the sudoers file. The chroot support, which is linked to this vulnerability, is set to be deprecated and removed in future releases.
