Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : cron vulnerability (USN-778-1)

High Nessus Plugin ID 38984


The remote Ubuntu host is missing a security-related patch.


It was discovered that cron did not properly check the return code of the setgid() and initgroups() system calls. A local attacker could use this to escalate group privileges. Please note that cron versions 3.0pl1-64 and later were already patched to address the more serious setuid() check referred to by CVE-2006-2607.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected cron package.
