Debian DLA-1025-1 : bind9 security update

medium Nessus Plugin ID 101536

Language:

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2017-3142

An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name may be able to circumvent TSIG authentication of AXFR requests via a carefully constructed request packet. A server that relies solely on TSIG keys for protection with no other ACL protection could be manipulated into :

 - providing an AXFR of a zone to an unauthorized recipient

 - accepting bogus NOTIFY packets

CVE-2017-3143

An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name for the zone and service being targeted may be able to manipulate BIND into accepting an unauthorized dynamic update.

For Debian 7 'Wheezy', these problems have been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u18.

We recommend that you upgrade your bind9 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
