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 computation that writes data past the end of the intended buffer; the computation is part of the image conversion module that handles Enhanced Metafile Format Plus (EMF+) data. The vulnerability is a result of an out of range pointer offset that is used to access sub-elements of an internal data structure. An attacker can potentially leverage the vulnerability to corrupt sensitive data or execute arbitrary code.

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 because of a computation that reads data that is past the end of the target buffer; the computation is a part of the JavaScript engine. 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.
