CVE-2016-4658 CRITICAL

Published: 2016-09-25 | Last Modified: 2026-06-17 | Status: Modified

Description

xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document.

Additional Descriptions (1)

xpointer.c en libxml2, en versiones anteriores a la 2.9.5 (tal y como se usa en Apple iOS en versiones anteriores a la 10, OS X en versiones anteriores a la 10.12, tvOS en versiones anteriores a la 10 y watchOS en versiones anteriores a la 3 y otros productos) no prohíbe los nodos de espacio de nombre en los rangos XPointer. Esto permite que atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (uso de memoria previamente liberada y corrupción de memoria) mediante un documento XML manipulado.
