Title
systemd: reexec state injection: fgets() on overlong lines leads to line splitting
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.
SSVC
Exploitation: none Automatable: no Technical Impact: total
