Name of the Vulnerable Software and Affected Versions Adobe Flash Player versions prior to 28.0.0.161

Description A use-after-free vulnerability was discovered in the Primetime SDK related to the media player's quality of service functionality. This issue occurs due to a dangling pointer, allowing a successful attack to lead to arbitrary code execution. The vulnerability can be exploited by a remote attacker to execute code remotely.

Recommendations For versions prior to 28.0.0.161, update to version 28.0.0.161 or later to resolve the issue. As a temporary workaround, consider disabling the quality of service functionality in the Primetime SDK until a patch is available. Restrict access to the media player's quality of service functionality to minimize the risk of exploitation.
