Adobe Flash Player versions 23.0.0.207 and earlier, 11.2.202.644 and earlier have an exploitable use after free vulnerability in the MovieClip class related to objects at multiple presentation levels. Successful exploitation could lead to arbitrary code execution.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
