vulnerability an attacker can send malformed messages to a server, if
this one accepts data from untrusted sources, and trigger a denial of
service attack.

For the stable distribution (wheezy), this problem has been fixed in
version 5.8.11-3+deb7u1.

For the unstable distribution (sid), this problem has been fixed in
