Debian DSA-3680-1 : bind9 - security update

high Nessus Plugin ID 93748
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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.


Upgrade the bind9 packages.

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