Description:
iDEFENSE has reported a vulnerability in GNU Radius, allowing malicious people to cause a Denial of Service.

The problem is that the "rad_print_request()" function fails to handle a packet with only an "Acct-Status-Type" attribute. This causes the radiusd to abend.

The vulnerability has been reported in version 1.1. Prior versions may also be affected.

Solution:
Update to version 1.2.
