3. Description:

The Apache Portable Runtime (APR) is a portability library used by the
Apache HTTP Server and other projects. It provides a free library of C data
structures and routines.

It was discovered that the apr_fnmatch() function used an unconstrained
recursion when processing patterns with the '*' wildcard. An attacker could
use this flaw to cause an application using this function, which also
accepted untrusted input as a pattern for matching (such as an httpd server
using the mod_autoindex module), to exhaust all stack memory or use an
excessive amount of CPU time when performing matching. (CVE-2011-0419)

Red Hat would like to thank Maksymilian Arciemowicz for reporting this
issue.

All apr users should upgrade to these updated packages, which contain a
backported patch to correct this issue. Applications using the apr library,
such as httpd, must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

703390 - CVE-2011-0419 apr: unconstrained recursion in apr_fnmatch
