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).
