Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.10 : freeradius vulnerabilities (USN-2122-1)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

It was discovered that FreeRADIUS incorrectly handled unix
authentication. A remote user could successfully authenticate with an
expired password. (CVE-2011-4966)

Pierre Carrier discovered that FreeRADIUS incorrectly handled rlm_pap
hash processing. An authenticated user could use this issue to cause
FreeRADIUS to crash, resulting in a denial of service, or possibly
execute arbitrary code. The default compiler options for affected
releases should reduce the vulnerability to a denial of service.

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 freeradius package.

Risk factor :

High / CVSS Base Score : 7.5
CVSS Temporal Score : 5.5
Public Exploit Available : false
