Background ========== Vixie Cron is a command scheduler with extended syntax over cron. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-process/vixie-cron < 4.1-r9 >= 4.1-r9 Description =========== Roman Veretelnikov discovered that Vixie Cron fails to properly check whether it can drop privileges accordingly if setuid() in do_command.c fails due to a user exceeding assigned resource limits. Impact ====== Local users can execute code with root privileges by deliberately exceeding their assigned resource limits and then starting a command through Vixie Cron. This requires resource limits to be in place on the machine. Workaround ========== There is no known workaround at this time. Resolution ========== All Vixie Cron users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-process/vixie-cron-4.1-r9" References ========== [ 1 ] CVE-2006-2607 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2607 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200606-07.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
