Debian DSA-3703-1 : bind9 - security update

Medium Nessus Plugin ID 94478

Synopsis

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

Description

Tony Finch and Marco Davids reported an assertion failure in BIND, a DNS server implementation, which causes the server process to terminate. This denial-of-service vulnerability is related to a defect in the processing of responses with DNAME records from authoritative servers and primarily affects recursive resolvers.

Solution

Upgrade the bind9 packages.

For the stable distribution (jessie), this problem has been fixed in version 1:9.9.5.dfsg-9+deb8u8.
