Descriptions

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.

Vulnerabilidad de agotamiento de pila en la función fnmatch implementada en apr_fnmatch.c en la librería de Apache Portable Runtime (APR) anterior a v1.4.3 y en Apache HTTP Server anterior a v2.2.18, y en fnmatch.c en libc en NetBSD v5.1, OpenBSD v4.8, FreeBSD, Apple Mac OS X v10.6, Oracle Solaris 10, y Android permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de CPU y memoria) a través de secuencias "*?" en el primer argumento, como se demostró con los ataques contra mod_autoindex en httpd.
