Descriptions

An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This vulnerability occurs as a result of a computation that reads data that is past the end of the target buffer; the computation is a part of Enhanced Metafile Format (EMF) processing within the image conversion module. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.

Se ha descubierto un problema en Adobe Acrobat y Reader: 2017.012.20098 y versiones anteriores, 2017.011.30066 y versiones anteriores, 2015.006.30355 y versiones anteriores y 11.0.22 y versiones anteriores. La vulnerabilidad ocurre como resultado de un cálculo que lee datos más allá del búfer objetivo; el cálculo forma parte del procesamiento del formato Enhanced Metafile Format (EMF) en el módulo de conversión de imagen. El uso de un puntero inválido (fuera de rango) durante el acceso a los campos de la estructura de datos interna provoca esta vulnerabilidad. Un ataque con éxito podría conducir a la exposición de datos sensibles.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Acrobat Pro DC. 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 parsing of EMR_STRETCHDIBITS structures within EMF files. When parsing the cySrc, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
