Vulnerability CVE-2017-16394

Vulnerability Name:

CVE-2017-16394 (CCN-134756)

Assigned:

2017-11-14

Published:

2017-11-14

Updated:

2017-12-15

Summary:

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 the WebCapture 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.
