Multiple Vulnerabilities in Adobe Products Could Allow for Arbitrary Code Execution

MS-ISAC ADVISORY NUMBER:

2021-088 - UPDATED

DATE(S) ISSUED:

07/13/2021 07/21/2021 - UPDATED

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Products, the most severe of which could allow for arbitrary code execution.  
  • Dimension is a 3D rendering and design software.
  • Illustrator is a vector graphics editor and design program.
  • Adobe Framemaker is a document processing software used to write and edit large or complex documents.
  • Acrobat and Reader is a family of application software and Web services mainly used to create, view, and edit PDF documents.
  • Bridge is a free digital asset management app. It is a mandatory component of Adobe Creative Suite, Adobe eLearning Suite, Adobe Technical Communication Suite and Adobe Photoshop CS2 through CS6.
  July 21 – UPDATED OVERVIEW:  
  • Photoshop is Adobe’s flagship image editing software.
  • Premiere Pro is a video editing software
  • After Effects is a graphics and visual effects software
  • Audition is a professional audio editing application that includes a non-destructive mixing and editing environment
  • Animator is a motion capture and animation tool that gives everyone a solution for intuitive animation
  • Prelude software is a video ingest and logging tool that helps you quickly tag and transcode raw footage from file-based cameras
  • Media Encoder is a software program by Adobe that is used to provide media content for the web and other sources
  Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

THREAT INTELLIGENCE:

There are currently no reports of these vulnerabilities being exploited in the wild.

RECOMMENDATIONS:

We recommend the following actions be taken:
  • Install the updates provided by Adobe immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
  • Apply the Principle of Least Privilege to all systems and services.
