CESA-2005:361: vixie-cron security update



An updated vixie-cron package that fixes various bugs and a security issue is now available. This update has been rated as having low security impact by the CentOS Security Response Team.

The vixie-cron package contains the Vixie version of cron. Cron is a standard UNIX daemon that runs specified programs at scheduled times. A bug was found in the way vixie-cron installs new crontab files. It is possible for a local attacker to execute the crontab command in such a way that they can view the contents of another user's crontab file. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-1038 to this issue. Additionally, this update addresses the following issues: o Fixed improper limits on filename and command line lengths o Improved PAM access control conforming to EAL certification requirements o Improved reliability when running in a chroot environment o Mail recipient name checking disabled by default, can be re-enabled o Added '-p' "permit all crontabs" option to disable crontab mode checking All users of vixie-cron should upgrade to this updated package, which contains backported patches and is not vulnerable to these issues.
