CVE-2018-18456
The function Object::isName() in Object.h (called from Gfx::opSetFillColorN) in Xpdf 4.00 allows remote attackers to cause a denial of service (stack-based buffer over-read) via a crafted pdf file, as demonstrated by pdftoppm.
Does this matter?
Lower severity and a low EPSS score (1.26%). Track it; it rarely justifies an emergency change on its own.
