Descriptions

An issue was discovered in Adobe Acrobat Reader 2018.009.20050 and earlier versions, 2017.011.30070 and earlier versions, 2015.006.30394 and earlier versions. This vulnerability occurs as a result of computation that reads data that is past the end of the target buffer; the computation occurs in the image conversion engine when processing Enhanced Metafile Format (EMF) data related to handling of bitmap rectangles. A successful attack can lead to sensitive data exposure.

Se ha descubierto un problema en Adobe Acrobat Reader 2018.009.20050 y anteriores, 2017.011.30070 y anteriores y 2015.006.30394 y anteriores. Esta vulnerabilidad ocurre como resultado de un cálculo que lee datos más allá del final del búfer objetivo; el cálculo ocurre en el motor de conversión de imágenes cuando gestiona datos Enhanced Metafile Format (EMF) relacionados con la gestión de rectángulos de bitmap. 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_ALPHABLEND records in EMF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
