  • 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)

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

Ubuntu 13.10
Ubuntu 12.10

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