CVE-2009-1862 Adobe Acrobat and Reader, Flash Player: command or code injection

In plain words: The program treats text it receives as instructions instead of plain data. The attacker can run commands on the machine — often the whole device is taken over.

Confirmed exploited by CISA on · US federal patch deadline Jun 22, 2022

What to do

  1. Install Adobe's security update for Acrobat and Reader, Flash Player. If no update exists, follow the vendor's workaround or stop using the product until one ships.
  2. Turn on automatic updates for the operating system and for Office, PDF and archive apps.
  3. Be careful with unexpected attachments — documents, .zip/.rar files and shortcuts are common bait.
  4. Use a normal (non-admin) account day to day and keep built-in protection like Microsoft Defender on.

Who is affected

Could reach you. This one is aimed at devices or apps of the kind people own.

What's at risk: Your files, saved passwords and accounts. Many of these let a program that is already running gain full administrator control.
