Echo: systemd: security update to 257.9-1~deb13u1+e2

medium Tenable Self-Hosted Container Security Plugin ID 462122

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an
 unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an
 assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is
 not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions
 older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known
 workarounds are available. (CVE-2026-29111)

Solution

Update the systemd library and its related packages to version 257.9-1~deb13u1+e2 or later.
