Descriptions

fxcodec/codec/fx_codec_jpx_opj.cpp in PDFium, as used in Google Chrome before 50.0.2661.75, does not properly implement the sycc420_to_rgb and sycc422_to_rgb functions, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via crafted JPEG 2000 data in a PDF document.

fxcodec/codec/fx_codec_jpx_opj.cpp en PDFium, como se utiliza en Google Chrome en versiones anteriores a 50.0.2661.75, no implementa correctamente las funciones sycc420_to_rgb y sycc422_to_rgb, lo que permite a atacantes remotos obtener información sensible de memoria de proceso o provocar una denegación de servicio (lectura fuera de rango) a través de datos JPEG 2000 manipulados en un documento PDF.

This vulnerability allows an attacker to leak sensitive information on vulnerable installations of Google Chrome. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of JPEG2000 images. A specially crafted JPEG2000 image embedded inside a PDF can force Google Chrome to read memory past the end of an allocated object. An attacker can leverage this vulnerability to disclose the contents of adjacent memory.
