Descriptions

The apr_strmatch_precompile function in strmatch/apr_strmatch.c in Apache APR-util before 1.3.5 allows remote attackers to cause a denial of service (daemon crash) via crafted input involving (1) a .htaccess file used with the Apache HTTP Server, (2) the SVNMasterURI directive in the mod_dav_svn module in the Apache HTTP Server, (3) the mod_apreq2 module for the Apache HTTP Server, or (4) an application that uses the libapreq2 library, which triggers a heap-based buffer underflow.

La función apr_strmatch_precompile en strmatch/apr_strmatch.c en Apache APR-util anteriores a v1.3.5 permite a los atacantes remotos causar una denegación de servicio (caída del demonio) a través de una entrada manipulada en 1) un fichero .htaccess utilizado con el Servidor Apache HTTP, (2) la directiva SVNMasterURI en el módulo mod_dav_svn en el Servidor Apache HTTP, (3) el módulo mod_apreq2 para el Servidor Apache HTTP, o (4) una aplicación que utiliza la librería libapreq2, relativa a un "bandera de desbordamiento inferior".
