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

Description The issue is related to an out-of-bounds read vulnerability when parsing a crafted file. This could result in a read past the end of an allocated memory structure, potentially allowing an attacker to bypass mitigations such as Address Space Layout Randomization (ASLR). Exploitation requires user interaction, specifically opening a malicious file. The vulnerability can lead to information disclosure through memory leak.

Recommendations For Adobe Acrobat Reader DC versions 22.001.2011x and earlier, update to a version later than 22.001.2011x to resolve the issue. For Adobe Acrobat Reader DC versions 20.005.3033x and earlier, update to a version later than 20.005.3033x to resolve the issue. For Adobe Acrobat Reader DC versions 17.012.3022x and earlier, update to a version later than 17.012.3022x to resolve the issue. As a temporary workaround, consider avoiding the opening of files from untrusted sources to minimize the risk of exploitation.
