Description
The issue is related to an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. This problem requires user interaction, as the victim must open a malicious file, specifically a specially crafted PDF file, to exploit the issue. The vulnerability is associated with a buffer overflow in memory, which can be exploited by an attacker to execute arbitrary code.
Recommendations
For Adobe Acrobat Reader DC versions 17.011.30204 through 21.007.20099: Update to a version later than 21.007.20099 to resolve the issue.
For Adobe Acrobat 2017 and Adobe Acrobat 2020: At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider avoiding the use of vulnerable font parsing functionality until a patch is available. Restrict access to malicious PDF files to minimize the risk of exploitation.
