Vulnerability from cvelistv5 – Published: 2018-10-26 14:00 – Updated: 2025-06-09 15:50
VLAI?
Summary
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239.
Severity ?
CWE
- fgets() can be confused by overly-long input strings. The first read will return a partial string and subsequent reads will begin as if it were a new line.
