CVE-2016-1017

Use-after-free vulnerability in the LoadVars.decode function in Adobe Flash Player before 18.0.0.343 and 19.x through 21.x before 21.0.0.213 on Windows and OS X and before 11.2.202.616 on Linux allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2016-1011, CVE-2016-1013, CVE-2016-1016, and CVE-2016-1031.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
