CVE-2018-16336
Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, a different vulnerability than CVE-2018-10999.
Does this matter?
Lower severity and a low EPSS score (2.73%). Track it; it rarely justifies an emergency change on its own.
