Adobe Flash Player Desktop Runtime 32.0.0.371 and earlier, Adobe Flash Player for Google Chrome 32.0.0.371 and earlier, and Adobe Flash Player for Microsoft Edge and Internet Explorer 32.0.0.330 and earlier have an use after free vulnerability. Successful exploitation could lead to arbitrary code execution.

A use-after-free vulnerability was discovered in Adobe Flash Player before 28.0.0.161. This vulnerability occurs due to a dangling pointer in the Primetime SDK related to media player handling of listener objects. A successful attack can lead to arbitrary code execution. This was exploited in the wild in January and February 2018.

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 metadata functionality. 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.

Adobe Flash Player has an exploitable memory corruption vulnerability in the MP4 atom parser. Successful exploitation could lead to arbitrary code execution. This affects 26.0.0.151 and earlier.

Adobe Security Bulletin APSB17-33 for Adobe Flash Player describes multiple flaws that can possibly lead to code execution when Flash Player is used to play a specially crafted SWF file.

Quoting from the APSB17-33:
