Debian DSA-2547-1 : bind9 - improper assert

high Nessus Plugin ID 62067

Language:

Synopsis

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

Description

It was discovered that BIND, a DNS server, does not handle DNS records properly which approach size limits inherent to the DNS protocol. An attacker could use crafted DNS records to crash the BIND server process, leading to a denial of service.

Solution

Upgrade the bind9 packages.

For the stable distribution (squeeze), this problem has been fixed in version 1:9.7.3.dfsg-1~squeeze7.
