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

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 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.

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
