Name of the Vulnerable Software and Affected Versions Adobe Acrobat Reader versions 22.001.20142 and earlier Adobe Acrobat Reader versions 20.005.30334 and earlier Adobe Acrobat Reader versions 17.012.30229 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, allowing an attacker to execute code in the context of the current user. Exploitation requires user interaction, such as opening a malicious file, and may enable an attacker to execute arbitrary code.

Recommendations For versions 22.001.20142 and earlier, update to a version later than 22.001.20142 to resolve the issue. For versions 20.005.30334 and earlier, update to a version later than 20.005.30334 to resolve the issue. For versions 17.012.30229 and earlier, update to a version later than 17.012.30229 to resolve the issue. As a temporary workaround, consider avoiding the use of the PDF parsing functionality until a patch is available.
