CVE-2011-1928 Information

Description

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.
