# Adobe Flash Player: Adobe Flash Player Dereferenced Pointer Vulnerability

Adobe Flash Player mishandles a dereferenced memory pointer, a memory-corruption bug. An attacker who gets a user to load crafted Flash content can run code on the machine.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Adobe Flash Player affected ? fixed ?

## How to check

Check whether any machine has Adobe Flash Player installed and what version it runs; the sources do not give a specific command.

## Fix

## From the sources

Adobe Flash Player before 13.0.0.258 and 14.x and 15.x before 15.0.0.239 on Windows and OS X and before 11.2.202.424 on Linux, Adobe AIR before 15.0.0.293, Adobe AIR SDK before 15.0.0.302, and Adobe AIR SDK & Compiler before 15.0.0.302 allow attackers to execute arbitrary code or cause a denial of service (invalid pointer dereference) via unspecified vectors.
