Name of the Vulnerable Software and Affected Versions Acrobat Reader DC versions 2021.005.20054 and earlier Acrobat Reader DC versions 2020.004.30005 and earlier Acrobat Reader DC versions 2017.011.30197 and earlier

Description The issue is related to a Null pointer dereference, which could allow an unauthenticated attacker to cause an application denial-of-service in the context of the current user. Exploitation requires user interaction, such as opening a malicious file. This could enable a remote attacker to achieve a denial-of-service.

Recommendations For versions 2021.005.20054 and earlier, update to a version later than 2021.005.20054 to resolve the issue. For versions 2020.004.30005 and earlier, update to a version later than 2020.004.30005 to resolve the issue. For versions 2017.011.30197 and earlier, update to a version later than 2017.011.30197 to resolve the issue. As a temporary workaround, consider avoiding the use of vulnerable Adobe Acrobat and Adobe Acrobat Reader versions until a patch is available.
