Mitigate the UDP traffic amplification vulnerability in OpenArena as per Debian DSA-2442-1 through essential security measures to protect against DoS attacks
It has been discovered that spoofed "getstatus" UDP requests are being sent by attackers to servers for use with games derived from the Quake 3 engine (such as openarena)

Summary

It has been discovered that spoofed "getstatus" UDP requests are being
sent by attackers to servers for use with games derived from the
Quake 3 engine (such as openarena). These servers respond with a
packet flood to the victim whose IP address was impersonated by the
attackers, causing a denial of service.

For the stable distribution (squeeze), this problem has been fixed in
version 0.8.5-5+squeeze2.

For the testing distribution (wheezy) and the unstable distribution
(sid), this problem has been fixed in version 0.8.5-6.

We recommend that you upgrade your openarena packages.
