Detail

Marek Vavruša and Lubos Slovak discovered that NSD, an authoritative domain name server, is not properly handling non-standard DNS packets. his can result in a NULL pointer dereference and crash the handling process. A remote attacker can abuse this flaw to perform denial of service attacks.

For the stable distribution (squeeze), this problem has been fixed in version 3.2.5-1.squeeze2.

For the testing distribution (wheezy), this problem will be fixed soon.
