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.
