CVE-2011-1928 – apr: DoS flaw in apr_fnmatch() due to fix for CVE-2011-0419

https://notcve.org/view.php?id=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. La implementación de fnmatch de apr_fnmatch.c de la librería Apache Portable Runtime (APR) 1.4.3 y 1.4.4, y el servidor Apache HTTP 2.2.18, permite a atacantes remotos provocar una denegación de servicio (bucle infinito) a través de una URI que no encaja en tipos de patrones de comodines sin especificar. Como se ha demostrado en ataques contra mod_autoindex en httpd cuando un patrón de configuración /*/WEB-INF/ es utilizado. NOTA: esta vulnerabilidad existe debido a una solución incorrecta a CVE-2011-0419. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=627182 http://lists.opensuse.org/opensuse-security-announce/2011-11/msg00011.html http://mail-archives.apache.org/mod_mbox/httpd-announce/201105.mbox/%3C4DD55092.3030403%40apache.org%3E http://mail-archives.apache.org/mod_mbox/www-announce/201105.mbox/%3c4DD55076.1060005%40apache.org%3e http://marc.info/?l=bugtraq&m=134987041210674&w=2 http://openwall.com/lists/oss-security/2011/05/19/10 http://openwall.com/lists/oss-security/2011 • CWE-399: Resource Management Errors •
