ISC BIND 9.x < 9.8.5 / 9.9.x < 9.9.3 Multiple Vulnerabilities

High Nessus Network Monitor Plugin ID 9876

Synopsis

The remote DNS server may be affected by multiple attack vectors.

Description

Versions of ISC BIND 9.x prior to 9.8.5, and 9.9.x prior to 9.9.3 are unpatched for a flaw that is triggered when handling a packet with a malformed options section. This may allow a remote attacker to trigger an assertion failure and cause a server to exit.

Solution

Upgrade ISC BIND to version 9.9.3 or later. If version 9.9.x cannot be obtained, version 9.8.5 is also patched for this vulnerability.
