Base vector

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

Name of the Vulnerable Software and Affected Versions systemd-journald versions v221 through v239

Description An out of bounds read was discovered in the way systemd-journald parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. The issue is related to an error in handling messages that end with a colon, which may lead to the disclosure of memory data.

Recommendations For versions v221 through v239, update to a version outside of this range to resolve the issue. As a temporary workaround, consider restricting access to the log parsing functionality until a patch is available.
