CVE-2021-44740
Acrobat Reader DC version 21.007.20099 (and earlier), 20.004.30017 (and earlier) and 17.011.30204 (and earlier) are affected by a Null pointer dereference vulnerability when parsing a specially crafted file.
Does this matter?
Lower severity and a low EPSS score (3.63%). Track it; it rarely justifies an emergency change on its own.
