An issue was discovered in Adobe Flash Player 27.0.0.183 and earlier versions. This vulnerability is an instance of a use after free vulnerability in the Primetime SDK. The mismatch between an old and a new object can provide an attacker with unintended memory access – potentially leading to code corruption, control-flow hijack, or an information leak attack. Successful exploitation could lead to arbitrary code execution.

Weakness

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
