Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/bind-9.10.4_P4-i586-1_slack14.2.txz: Upgraded.
 This update fixes a denial-of-service vulnerability. A defect in BIND's
 handling of responses containing a DNAME answer can cause a resolver to exit
 after encountering an assertion failure in db.c or resolver.c. A server
 encountering either of these error conditions will stop, resulting in denial
 of service to clients. The risk to authoritative servers is minimal,
 recursive servers are chiefly at risk.
 For more information, see:

 (* Security fix *)
+--------------------------+");
