CVE-2018-15686 (GCVE-0-2018-15686)

Vulnerability from cvelistv5 – Published: 2018-10-26 14:00 – Updated: 2025-06-09 15:50

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.

Severity

7 (High)


                        
                          CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

SSVC

Exploitation: none Automatable: no Technical Impact: total

CISA Coordinator · CISA-ADP (v2.0.3)

Decision recorded 2025-06-09 15:50 UTC

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.
CWE-502 - Deserialization of Untrusted Data

Vulnerability from cvelistv5 – Published: 2019-01-14 22:00 – Updated: 2024-08-05 10:39

Summary

It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable.

Severity
