Descriptions

The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.

La función xz_decomp en xzlib.c en libxml2 2.9.1 no detecta adecuadamente los errores de compresión, lo que permite a atacantes dependientes del contexto causar una denegación de servicio (cuelgue del proceso) a través de datos XML manipulados.

A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to crash.
