In short

A use-after-free vulnerability in Adobe Flash Player and AIR allows attackers to execute arbitrary code on Windows, macOS, and Linux systems. This occurs when the software tries to use memory that has already been freed, potentially allowing attackers to take complete control of the affected computer.

Technical detail

Use-after-free vulnerability (CWE-416) in Adobe Flash Player (versions before 18.0.0.329, 19.x/20.x before 20.0.0.306 on Windows/macOS, before 11.2.202.569 on Linux) and Adobe AIR/AIR SDK/AIR SDK & Compiler (before 20.0.0.260) exploitable via unspecified vectors to achieve arbitrary code execution. The vulnerability requires user interaction to trigger the vulnerable code path.
