CVE-2019-20016
libmysofa before 2019-11-24 does not properly restrict recursive function calls, as demonstrated by reports of stack consumption in readOHDRHeaderMessageDatatype in dataobject.c and directblockRead in fractalhead.c.
Does this matter?
Lower severity and a low EPSS score (1.95%). Track it; it rarely justifies an emergency change on its own.
Description
