CentOS Errata and Security Advisory CESA-2011:0507
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.
