USN-3369-1: FreeRADIUS vulnerabilities

27 July 2017

Several security issues were fixed in FreeRADIUS.



  • freeradius - high-performance and highly configurable RADIUS server


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
Ubuntu 16.04
Ubuntu 14.04

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