Debian DSA-3680-1 : bind9 - security update

High Nessus Plugin ID 93748

Synopsis

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

Description

Two vulnerabilities were reported in BIND, a DNS server.

- CVE-2016-2775 The lwresd component in BIND (which is not enabled by default) could crash while processing an overlong request name. This could lead to a denial of service.

- CVE-2016-2776 A crafted query could crash the BIND name server daemon, leading to a denial of service. All server roles (authoritative, recursive and forwarding) in default configurations are affected.

Solution

Upgrade the bind9 packages.

For the stable distribution (jessie), these problems have been fixed in version 1:9.9.5.dfsg-9+deb8u7.
