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 an attacker to read past the end of an allocated memory structure. This could be leveraged to bypass mitigations such as Address Space Layout Randomization (ASLR). Exploitation requires user interaction, specifically opening a malicious file. The vulnerability can result in a memory leak.

Recommendations For versions 22.001.2011x and earlier, update to a version that fixes the out-of-bounds read vulnerability. For versions 20.005.3033x and earlier, update to a version that fixes the out-of-bounds read vulnerability. For versions 17.012.3022x and earlier, update to a version that fixes the out-of-bounds read vulnerability. As a temporary workaround, consider avoiding the use of crafted files that could trigger the out-of-bounds read vulnerability until a patch is available.
