Synopsis:    Low: apr security update
Issue Date:  2011-05-31
CVE Numbers: CVE-2011-1928


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 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.
