Description
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.
Analysis
systemd (PID 1) contains a denial-of-service vulnerability triggered by malformed IPC API calls from unprivileged users that causes the service manager to assert and freeze. On versions v249 and earlier, the same vulnerability manifests as stack buffer overwriting with attacker-controlled data, potentially enabling code execution; versions v250 and newer include a safety check that converts this to a non-exploitable assertion failure. …
