Debian DSA-3162-1 : bind9 - security update

medium Nessus Plugin ID 81409

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Jan-Piet Mens discovered that the BIND DNS server would crash when processing an invalid DNSSEC key rollover, either due to an error on the zone operator's part, or due to interference with network traffic by an attacker. This issue affects configurations with the directives 'dnssec-validation auto;' (as enabled in the Debian default configuration) or 'dnssec-lookaside auto;'.

Solution

Upgrade the bind9 packages.

For the stable distribution (wheezy), this problem has been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u4.
