Base vector

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

Name of the Vulnerable Software and Affected Versions systemd version 259

Description In systemd 259, the systemd-journald component can transmit ANSI escape sequences to the terminals of arbitrary users when a 'logger -p emerg' command is executed, provided that ForwardToWall=yes is configured. This can potentially lead to unexpected behavior or display manipulation for users.

Recommendations Update to a newer version that contains a fix for this vulnerability. As a temporary workaround, consider setting ForwardToWall=no in the systemd configuration to prevent the transmission of ANSI escape sequences to all user terminals.
