Description A path traversal vulnerability affects Adobe Acrobat and Reader, allowing an unauthenticated attacker to achieve arbitrary code execution in the context of the current user. This issue requires user interaction, where a victim must open a malicious file, specifically a specially crafted PDF file, to exploit the vulnerability. The vulnerability is related to incorrect restriction of a pathname to a directory with limited access.
Recommendations For Acrobat Reader DC versions 2021.005.20054 and earlier, update to a version later than 2021.005.20054 to resolve the issue. For Acrobat Reader DC versions 2020.004.30005 and earlier, update to a version later than 2020.004.30005 to resolve the issue. For Acrobat Reader DC versions 2017.011.30197 and earlier, update to a version later than 2017.011.30197 to resolve the issue. As a temporary workaround, consider avoiding the use of PDF files from untrusted sources until a patch is available.
