# Double free vulnerability in Adobe Flash Player before 11.7.700.269 and 11.8.x through 12.0.x before 12.0.0.70 on…

Adobe Flash Player has a double free memory bug that lets a remote attacker run arbitrary code. CISA lists it as actively exploited in the wild.

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

## Affected

- vendor:adobe flash player affected < 11.7.700.269 fixed 11.7.700.269

- vendor:adobe flash player affected < 11.2.202.341 fixed 11.2.202.341
- vendor:adobe air affected < 4.0.0.1628 fixed 4.0.0.1628
- vendor:opensuse affected = 11.4 fixed ?
- vendor:opensuse affected = 12.3 fixed ?
- vendor:opensuse affected = 13.1 fixed ?
- vendor:suse linux enterprise desktop affected = 11 fixed ?
- vendor:redhat enterprise linux desktop affected = 5.0 fixed ?
- vendor:redhat enterprise linux desktop affected = 6.0 fixed ?
- vendor:redhat enterprise linux eus affected = 6.5 fixed ?
- vendor:redhat enterprise linux server affected = 5.0 fixed ?
- vendor:redhat enterprise linux server affected = 6.0 fixed ?
- vendor:redhat enterprise linux server aus affected = 6.5 fixed ?
- vendor:redhat enterprise linux workstation affected = 5.0 fixed ?
- vendor:redhat enterprise linux workstation affected = 6.0 fixed ?
- vendor:Adobe Flash Player affected ? fixed ?

## How to check

Check whether Adobe Flash Player is installed on the machine (unknown for exact path or version command in sources).

## Fix

Remove Adobe Flash Player; the product is end-of-life and no longer receives fixes (per CISA required action).

## From the sources

Double free vulnerability in Adobe Flash Player before 11.7.700.269 and 11.8.x through 12.0.x before 12.0.0.70 on Windows and Mac OS X and before 11.2.202.341 on Linux, Adobe AIR before 4.0.0.1628 on Android, Adobe AIR SDK before 4.0.0.1628, and Adobe AIR SDK & Compiler before 4.0.0.1628 allows remote attackers to execute arbitrary code via unspecified vectors, as exploited in the wild in February 2014.
