[slackware-security] bind (SSA:2017-011-01)

New bind packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1,
14.2, and -current to fix a security issue.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/bind-9.10.4_P5-i586-1_slack14.2.txz: Upgraded.
This update fixes a denial-of-service vulnerability. An error in handling
certain queries can cause an assertion failure when a server is using the
nxdomain-redirect feature to cover a zone for which it is also providing
authoritative service. A vulnerable server could be intentionally stopped
by an attacker if it was using a configuration that met the criteria for
the vulnerability and if the attacker could cause it to accept a query
that possessed the required attributes.
Please note: This vulnerability affects the "nxdomain-redirect"
feature,
which is one of two methods of handling NXDOMAIN redirection, and is only
available in certain versions of BIND. Redirection using zones of type
"redirect" is not affected by this vulnerability.
For more information, see:
