Description
The issue is a Heap-based Buffer Overflow that allows an unauthenticated attacker to achieve arbitrary code execution in the context of the current user. Exploitation requires user interaction, where a victim must open a malicious file, specifically a specially crafted PDF file. This can enable a remote attacker to execute arbitrary code in the context of the current user.
Recommendations
For Adobe Acrobat Reader DC versions 2021.001.20150 and earlier, update to a version later than 2021.001.20150 to resolve the issue.
For Adobe Acrobat Reader DC versions 2020.001.30020 and earlier, update to a version later than 2020.001.30020 to resolve the issue.
For Adobe Acrobat Reader DC versions 2017.011.30194 and earlier, update to a version later than 2017.011.30194 to resolve the issue.
As a temporary workaround, consider avoiding the use of Adobe Acrobat Reader DC to open PDF files from untrusted sources until a patch is available.
