Description The issue is related to an Integer Underflow or Wraparound that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction, where a victim must open a malicious file. This allows an attacker to execute arbitrary code.
Recommendations For Adobe Acrobat Reader versions 23.001.20093 and earlier, update to a version later than 23.001.20093 to resolve the issue. For Adobe Acrobat Reader versions 20.005.30441 and earlier, update to a version later than 20.005.30441 to resolve the issue. For Adobe Acrobat 2020 and Adobe Acrobat Reader 2020, update to a newer version that includes the fix for the Integer Underflow vulnerability. As a temporary workaround, consider avoiding the use of Doc Object related functionality in Adobe Acrobat Reader DC until a patch is available.
