NVD Description

Note: Versions mentioned in the description apply only to the upstream flash-plugin package and not the flash-plugin package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

An Out-of-bounds Read issue was discovered in Adobe Flash Player before 28.0.0.137. This vulnerability occurs because of computation that reads data that is past the end of the target buffer. 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.
