Not long ago, httpd package updates were issued to clamp down on a denial of
service bug that’s seen some action in the wild. New packages are available
for Slackware 12.0, 12.1, 12.2, 13.0, 13.1, 13.37, and -current.

Here are the details from the Slackware 13.37 ChangeLog:

patches/packages/httpd-2.2.20-i486-1_slack13.37.txz: Upgraded.
SECURITY: CVE-2011-3192 (cve.mitre.org)
core: Fix handling of byte-range requests to use less memory, to avoid
denial of service. If the sum of all ranges in a request is larger than
the original file, ignore the ranges and send the complete file.
PR 51714. [Stefan Fritsch, Jim Jagielski, Ruediger Pluem, Eric Covener]
