NetworkManager-libreswan plugin, which adds functionality to NetworkManager for connecting to VPNs compatible with servers based on Libreswan and Cisco IPsec, has a vulnerability (CVE-2024-9050) that can be exploited by a local user to elevate privileges. The vulnerability has been fixed in NetworkManager-libreswan update 1.2.24. You can track updates in distributions on the following pages: Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora. <\/p>\n

The issue is caused by improper configuration checks VPN<\/a>, mille m\u00e4\u00e4rab kohalik mitteprivileegitud kasutaja ja edastatakse otse Libreswanile \u00fchenduse aktiveerimise katse ajal.

Another vulnerability has been discovered in the background process guix-daemon, used in distributions based on the GNU Guix package manager. This vulnerability poses a risk to multi-user systems and allows a local user to acquire the privileges of any user performing package builds (build user) and modify the build output. The essence of the vulnerability is that an attacker can start a derived build, and if the build process is interrupted, already created suid-files remain accessible to other users in the system. After that, the attacker can use the created suid-file to pause the build process, open any file via \/proc\/$PID\/fd with the privileges of the user performing the build, and overwrite files with the build results.
