Description Laura Pardo 2018-11-12 22:41:00 UTC

A flaw was found in Exiv2 0.26. A heap-based buffer over-read in Exiv2::IptcParser::decode in iptc.cpp (called from psdimage.cpp in the PSD image reader). This could lead to a denial of service caused by an integer overflow via a crafted PSD image file.
