Debian DSA-3304-1 : bind9 - security update

high Nessus Plugin ID 84599

Language:

Synopsis

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

Description

Breno Silveira Soares of Servico Federal de Processamento de Dados (SERPRO) discovered that the BIND DNS server is prone to a denial of service vulnerability. A remote attacker who can cause a validating resolver to query a zone containing specifically constructed contents can cause the resolver to terminate with an assertion failure, resulting in a denial of service to clients relying on the resolver.

Solution

Upgrade the bind9 packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u5.

For the stable distribution (jessie), this problem has been fixed in version 1:9.9.5.dfsg-9+deb8u1.
