Name of the Vulnerable Software and Affected Versions Adobe Acrobat and Reader versions 2017.012.20098 and earlier Adobe Acrobat and Reader versions 2017.011.30066 and earlier Adobe Acrobat and Reader versions 2015.006.30355 and earlier Adobe Acrobat and Reader versions 11.0.22 and earlier

Description The issue occurs due to a computation that reads data past the end of the target buffer in the JavaScript engine, specifically in the part that handles annotation abstraction. This happens because of an invalid pointer offset used during access of internal data structure fields. A successful attack can lead to sensitive data exposure. Additionally, this vulnerability allows attackers to execute code remotely.

Recommendations For versions 2017.012.20098 and earlier, update to a version later than 2017.012.20098. For versions 2017.011.30066 and earlier, update to a version later than 2017.011.30066. For versions 2015.006.30355 and earlier, update to a version later than 2015.006.30355. For versions 11.0.22 and earlier, update to a version later than 11.0.22.
