CentOS Errata and Security Advisory CESA-2011:0844
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.
The fix for CVE-2011-0419 (released via RHSA-2011:0507) introduced an
infinite loop flaw in the apr_fnmatch() function when the APR_FNM_PATHNAME
matching flag was used. A remote attacker could possibly use this flaw to
cause a denial of service on an application using the apr_fnmatch()
function. (CVE-2011-1928)
Note: This problem affected httpd configurations using the “Location”
directive with wildcard URLs. The denial of service could have been
triggered during normal operation; it did not specifically require a
malicious HTTP request.
This update also addresses additional problems introduced by the rewrite of
the apr_fnmatch() function, which was necessary to address the
CVE-2011-0419 flaw.
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.
