CVE-2019-17533
Mat_VarReadNextInfo4 in mat4.c in MATIO 1.5.17 omits a certain '\0' character, leading to a heap-based buffer over-read in strdup_vprintf when uninitialized memory is accessed.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
