Vixie cron: Denial of service

Vixie cron: Denial of service A vulnerability has been found in Vixie cron, allowing local attackers to conduct symlink attacks. vixie-cron 2013-11-07 2013-11-07 308055 local 4.1-r14 4.1-r14

Paul Vixie’s cron daemon, a fully featured crond implementation.

Vixie cron contains a race condition relating to atime and mtime values of temporary files.

A local attacker could change the modification time of files, possibly resulting in a Denial of Service condition via a symlink attack.

There is no known workaround at this time.

All Vixie cron users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-process/vixie-cron-4.1-r14"
