Bug#911487: teeworlds: remote DOS by forging connection packets

[Markus Koschany]

Package: teeworlds-server
Version: 0.6.4+dfsg-1
Severity: grave
Tags: security

It was discovered that a Teeworlds server could be made inaccessible
by forging connection packets. This made it look like the server was
always full thus access to the server was effectively denied. My own
private server was recently affected by this. The only way to mitigate
this attack is to change the server port. Apparently this issue was
fixed in version 0.6.5.
