CVE-2017-5503
The dec_clnpass function in libjasper/jpc/jpc_t1dec.c in JasPer 1.900.27 allows remote attackers to cause a denial of service (invalid memory write and crash) or possibly have unspecified other impact via a crafted image.
Does this matter?
Lower severity and a low EPSS score (1.76%). Track it; it rarely justifies an emergency change on its own.
