Type:
security
Severity:
Important
Release date:
2026-09-01 14:30:57 UTC
Description:
- CVE-2026-72694: refuse a symbolic link at the pid file path, create the file with O_CREAT|O_EXCL and chown the open handle rather than the path. Started as root in daemon mode, mrtg created and chowned the pid file before dropping privileges, so a pre-placed symlink could have root chown an arbitrary file to the daemon user.
CVEs fixed:
Updated packages:
  • mrtg-2.17.7-11.el9_6.tuxcare.els1.x86_64.rpm
