CVE-2017-14121
The DecodeNumber function in unrarlib.c in unrar 0.0.1 (aka unrar-free or unrar-gpl) suffers from a NULL pointer dereference flaw triggered by a crafted RAR archive.
Does this matter?
Lower severity and a low EPSS score (1.12%). Track it; it rarely justifies an emergency change on its own.
