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. The vulnerability is caused by a buffer over-read in the exif processing module for a PNG file (during XPS conversion). Invalid input leads to a computation where pointer arithmetic results in a location outside valid memory locations belonging to the buffer. An attack can be used to obtain sensitive information, such as object heap addresses, etc.

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 se debe a una sobrelectura de búfer en el módulo de procesamiento exif para un archivo PNG (durante la conversión XPS). Las entradas no válidas conducen a un cálculo en el que la aritmética de punteros resulta en una ubicación fuera de las ubicaciones de memoria válidas pertenecientes al búfer. Un ataque puede ser empleado para obtener información sensible, como direcciones de la memoria dinámica (heap) del objeto, etc.

This vulnerability allows remote attackers to disclose sensitive information 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 the tEXT chunk in PNG images embedded inside XPS files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
