CVE-2017-12800
The EBML_FindNextElement function in ebmlmain.c in libebml2 through 2012-08-26 allows remote attackers to cause a denial of service (Null pointer dereference and application crash) via a crafted mkv file.
Does this matter?
Lower severity and a low EPSS score (2.42%). Track it; it rarely justifies an emergency change on its own.
