Multiple Vulnerabilities in Adobe Products Could Allow for Arbitrary Code Execution

ITS ADVISORY NUMBER:

2022-006 - UPDATED

DATE(S) ISSUED:

Wednesday, January 12, 2022

DATE UPDATED:

Wednesday, March 23, 2022

SUBJECT:

Multiple Vulnerabilities in Adobe Products could allow for Arbitrary Code Execution

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for Arbitrary Code Execution.

Acrobat and Reader is a family of application software and Web services mainly used to create, view, and edit PDF documents.
Illustrator is a vector graphics editor and design program.
Bridge is a digital asset management application.
Adobe InCopy is a professional word processor.
InDesign is an industry-leading layout and page design software for print and digital media.

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.

March 23 - UPDATED OVERVIEW:
Two additional vulnerabilities have been reported in Adobe Acrobat and Adobe Reader which could allow for remote code execution.

THREAT INTELLIGENCE:

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

SYSTEMS AFFECTED:

Acrobat DC and Acrobat Reader DC 21.007.20099 and earlier versions for Windows.
Acrobat DC and Acrobat Reader DC 21.007.20099 and earlier versions for macOS.

ACTIONS:

After appropriate testing, immediately install the updates provided by Adobe.
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.
