Synopsis
The remote Red Hat host is missing a security update for bind.Description
The remote Redhat Enterprise Linux 5 / 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:1944 advisory.The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols.
BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.
Security Fix(es):
* A denial of service flaw was found in the way BIND constructed a response to a query that met certain criteria. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS request packet. (CVE-2016-2776)
Red Hat would like to thank ISC for reporting this issue.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL bind package based on the guidance in RHSA-2016:1944.See Also
