RHSA-2011:0507: apr security update (Moderate)  

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.
