Allocation of Resources Without Limits or Throttling SNYK-DEBIAN9-SYSTEMD-305082

[github-actions]

NVD Description

Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.

An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable.

Remediation

Upgrade Debian:9 systemd to version 232-25+deb9u7 or higher.
