[slackware-security] apr/apr-util (SSA:2011-133-01)
New apr and apr-util packages are available for Slackware 11.0, 12.0, 12.1,
12.2, 13.0, 13.1, 13.37, and -current to fix a security issue.
Here are the details from the Slackware 13.37 ChangeLog:
+--------------------------+
patches/packages/apr-1.4.4-i486-1_slack13.37.txz: Upgraded.
This fixes a possible denial of service due to an unconstrained, recursive
invocation of apr_fnmatch(). This function has been reimplemented using a
non-recursive algorithm. Thanks to William Rowe.
For more information, see:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-0419
(* Security fix *)
patches/packages/apr-util-1.3.11-i486-1_slack13.37.txz: Upgraded.

Where to find the new packages:
+-----------------------------+
HINT: Getting slow download speeds from ftp.slackware.com?
Give slackware.osuosl.org a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading
directly from ftp.slackware.com.
Thanks to the friendly folks at the OSU Open Source Lab
(http://osuosl.org) for donating additional FTP and rsync hosting
to the Slackware project! :-)
Also see the "Get Slack" section on http://slackware.com for
additional mirror sites near you.
