CVE-2018-8975
The pm_mallocarray2 function in lib/util/mallocvar.c in Netpbm through 10.81.03 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, as demonstrated by pbmmask.
Does this matter?
Lower severity and a low EPSS score (1.66%). Track it; it rarely justifies an emergency change on its own.
