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

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

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.

Solution :

Update the affected cron package.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
