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

Another vulnerability has been identified 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 gain privileges of any user compiling packages (build user) and modify the build output. The essence of the vulnerability is that the attacker can start a derivative build, and if the build process is interrupted, the 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 through \/proc\/$PID\/fd with the privileges of the user compiling and overwrite files with the build results.
