Use After Free
Use-after-free vulnerability in Adobe Flash Player before 220.127.116.11 on Windows and OS X and before 18.104.22.1683 on Linux allows remote attackers to execute arbitrary code via unspecified vectors, as exploited in the wild in October 2016.
CWE-416 - Use After Free
Use-after-free (UaF) vulnerability occurs when the application is using a pointer to memory that has been freed. Any attempt to read/write to a buffer after it is de-allocated allows memory corruption, sensitive information exposure, and can potentially lead to arbitrary code execution.
