Use-after-free vulnerability in Adobe Flash Player before 18.0.0.375 and 19.x through 23.x before 23.0.0.162 on Windows and OS X and before 11.2.202.635 on Linux allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2016-4272, CVE-2016-4279, CVE-2016-6921, CVE-2016-6923, CVE-2016-6925, CVE-2016-6926, CVE-2016-6927, CVE-2016-6930, CVE-2016-6931, and CVE-2016-6932.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
