Ubuntu Security Notice USN-2122-1

freeradius vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in FreeRADIUS.

Software Description:
- freeradius: high-performance and highly configurable RADIUS server

Details:

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. (CVE-2014-2015)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
freeradius 2.1.12+dfsg-1.2ubuntu5.1

Ubuntu 12.10:
freeradius 2.1.12+dfsg-1.1ubuntu0.1

Ubuntu 12.04 LTS:
freeradius 2.1.10+dfsg-3ubuntu0.12.04.2

Ubuntu 10.04 LTS:
freeradius 2.1.8+dfsg-1ubuntu1.1

In general, a standard system update will make all the necessary changes.
