Descriptions

Artifex MuPDF 1.11 allows attackers to execute arbitrary code or cause a denial of service via a crafted .xps file, related to a "User Mode Write AV near NULL starting at wow64!Wow64NotifyDebugger+0x000000000000001d" on Windows. This occurs because read_zip_dir_imp in fitz/unzip.c does not check whether size fields in a ZIP entry are negative numbers.

La versión 1.11 de Artifex MuPDF permite que los atacantes ejecuten código arbitrario o que provoquen una denegación de servicio mediante un archivo .xps manipulado, relacionado con "User Mode Write AV comenzando en wow64!Wow64NotifyDebugger+0x000000000000001d" en Windows. Esto ocurre porque read_zip_dir_imp en fitz/unzip.c no comprueba si los campos de tamaño en una entrada ZIP son números negativos.
