Description David Walser 2016-01-20 01:55:23 CET

Upstream has issued advisories today (January 19):
https://kb.isc.org/article/AA-01335
https://kb.isc.org/article/AA-01336

These are remotely exploitable denial of service vulnerabilities.  The first is high severity.

Updated packages uploaded for Mageia 5 and Cauldron.

Advisory:
========================

Updated bind packages fix security vulnerabilities:

In ISC BIND before 9.10.3-P3, a buffer size check used to guard against
overflow could cause named to exit with an INSIST failure In apl_42.c
(CVE-2015-8704).

In ISC BIND before 9.10.3-P3, errors can occur when OPT pseudo-RR data or ECS
options are formatted to text.  In 9.10.3 through 9.10.3-P2, the issue may
result in a REQUIRE assertion failure in buffer.c, causing a crash.  This can
be avoided in named by disabling debug logging (CVE-2015-8705).
