postfix_groups.pl in Postfix 2.5.2 allows local users to overwrite arbitrary files via a symlink attack on the (1) /tmp/postfix_groups.stdout, (2) /tmp/postfix_groups.stderr, and (3) /tmp/postfix_groups.message temporary files. NOTE: the vendor disputes this vulnerability, stating "This is not a real issue ... users would have to edit a script under /usr/lib to enable it.

Security readout for executives and security teams

This old Postfix issue alleges a local file-overwrite risk in postfix_groups.pl through unsafe temporary files. It matters mainly where untrusted local users can access the server and the script is actually enabled. The vendor disputed the report, saying the script would need local modification first. Likely exposure is narrow: legacy Postfix 2.5.2 systems where postfix_groups.pl exists, has been enabled or modified, and can be triggered in a context useful to local users. The source bundle does not confirm default exposure. Treat as a legacy hygiene item, not an emergency, unless you still operate shared-user mail servers with old Postfix packages. Prioritize inventory and upgrade planning over incident response absent stronger exploitation evidence. Mitigation focus: Check vendor and distribution guidance for Postfix package status.; Confirm whether postfix_groups.pl is present, modified, or invoked locally.; Avoid enabling disputed helper scripts without reviewing temporary-file handling..
