Adobe Flash Player Incorrect Default Permissions Vulnerability

Adobe · Flash Player

End of lifeAdobe Flash Player reached on 31 Dec 2020. No patch is coming: remove or isolate it.

Summary

The Firefox sandbox in Adobe Flash Player, a component of the product on Windows, Mac OS X and Linux, does not properly restrict privileges, which is an improper privilege management flaw. A remote attacker can exploit it to execute arbitrary code by supplying crafted SWF content, with no authentication required and only a user interaction needed to trigger it.

Official description · NVD

The Firefox sandbox in Adobe Flash Player before 10.3.183.67 and 11.x before 11.6.602.171 on Windows and Mac OS X, and before 10.3.183.67 and 11.x before 11.2.202.273 on Linux, does not properly restrict privileges, which makes it easier for remote attackers to execute arbitrary code via crafted SWF content, as exploited in the wild in February 2013.
