CVE-2011-1928
The fnmatch implementation in apr_fnmatch.c in the Apache Portable
Runtime (APR) library 1.4.3 and 1.4.4, and the Apache HTTP Server
2.2.18, allows remote attackers to cause a denial of service (infinite
loop) via a URI that does not match unspecified types of wildcard
patterns, as demonstrated by attacks against mod_autoindex in httpd
when a /*/WEB-INF/ configuration pattern is used.  NOTE: this issue
exists because of an incorrect fix for CVE-2011-0419.

CVE-2011-0419
Stack consumption vulnerability in the fnmatch implementation in
apr_fnmatch.c in the Apache Portable Runtime (APR) library before
1.4.3 and the Apache HTTP Server before 2.2.18, and in fnmatch.c in
libc in NetBSD 5.1, OpenBSD 4.8, FreeBSD, Apple Mac OS X 10.6, Oracle
Solaris 10, and Android, allows context-dependent attackers to cause a
denial of service (CPU and memory consumption) via *? sequences in the
first argument, as demonstrated by attacks against mod_autoindex in
httpd.");
