Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/glibc-2.17-i486-11_slack14.1.txz: Rebuilt.
 This update provides a patch to fix the stack-based buffer overflow in
 libresolv that could allow specially crafted DNS responses to seize
 control of execution flow in the DNS client (CVE-2015-7547). However,
 due to a patch applied to Slackware's glibc back in 2009 (don't use the
 gethostbyname4() lookup method as it was causing some cheap routers to
 misbehave), we were not vulnerable to that issue. Nevertheless it seems
 prudent to patch the overflows anyway even if we're not currently using
 the code in question. Thanks to mancha for the backported patch.
