CVE-2020-1971 – EDIPARTYNAME NULL pointer dereference

https://notcve.org/view.php?id=CVE-2020-1971

08 Dec 2020 — The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. • https://github.com/MBHudson/CVE-2020-1971 • CWE-476: NULL Pointer Dereference •
