How to fix?

Upgrade Debian:12 exim4 to version 4.72-4 or higher.

NVD Description

Note: Versions mentioned in the description apply to the upstream exim4 package. See How to fix? for Debian:12 relevant versions.

The open_log function in log.c in Exim 4.72 and earlier does not check the return value from (1) setuid or (2) setgid system calls, which allows local users to append log data to arbitrary files via a symlink attack.
