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

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

- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in FreeRADIUS.

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

Details:

Guido Vranken discovered that FreeRADIUS incorrectly handled memory when
decoding packets. A remote attacker could use this issue to cause
FreeRADIUS to crash or hang, resulting in a denial of service, or possibly
execute arbitrary code.

Update instructions:

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

Ubuntu 17.04:
  freeradius                      3.0.12+dfsg-4ubuntu1.2

Ubuntu 16.04 LTS:
  freeradius                      2.2.8+dfsg-0.1ubuntu0.1

Ubuntu 14.04 LTS:
  freeradius                      2.1.12+dfsg-1.2ubuntu8.2

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