Name of the Vulnerable Software and Affected Versions Adobe Acrobat Reader versions 22.002.20212 and earlier Adobe Acrobat Reader versions 20.005.30381 and earlier

Description The issue is a Stack-based Buffer Overflow that could result in arbitrary code execution in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file. This allows an attacker to execute arbitrary code.

Recommendations For versions 22.002.20212 and earlier, update to a version later than 22.002.20212 to resolve the issue. For versions 20.005.30381 and earlier, update to a version later than 20.005.30381 to resolve the issue. As a temporary workaround, consider avoiding the use of Adobe Acrobat Reader to open files from untrusted sources until a patch is available.
