Vulnerability from fkie_nvd - Published: 2019-01-11 20:29 - Updated: 2026-06-17 01:44
Summary
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.
