Ubuntu priority
Cvss 3 Severity Score
An integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via a crafted PNG image file, because PngImage::readMetadata mishandles a zero value for iccOffset.

Notes
leosilva
in Xenial, Bionic, Cosmic and Disco, the poc does SIGSEGV but instead raise the Error(21) "Failed to read input data", what I believe is the expected behavior. Also, iccOffset code is not-present.
