Ubuntu 11.04 / 11.10 / 12.04 LTS : freeradius vulnerability (USN-1585-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Timo Warns discovered that FreeRADIUS incorrectly handled certain long
timestamps in client certificates. A remote attacker could exploit
this flaw and cause the FreeRADIUS server 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 :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
