CVE-2018-11416
jpegoptim.c in jpegoptim 1.4.5 (fixed in 1.4.6) has an invalid use of realloc() and free(), which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
