Description
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. NOTE: a download of v0.9 after 2019-12-06 should fully remediate this issue.
