Name of the Vulnerable Software and Affected Versions Acrobat Reader DC versions 22.001.2011x and earlier Acrobat Reader DC versions 20.005.3033x and earlier Acrobat Reader DC versions 17.012.3022x and earlier

Description The issue is an out-of-bounds read vulnerability that occurs when parsing a crafted file, potentially allowing a read past the end of an allocated memory structure. This could be leveraged by an attacker to bypass mitigations such as ASLR. Exploitation requires user interaction, specifically opening a malicious file.

Recommendations For versions 22.001.2011x and earlier, consider disabling the ability to open crafted files until a patch is available. For versions 20.005.3033x and earlier, restrict access to potentially malicious files to minimize the risk of exploitation. For versions 17.012.3022x and earlier, avoid using the affected parsing functionality until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
