Description Laura Pardo 2018-02-14 13:03:21 UTC

A flaw was found in Exiv2 0.26. There is a integer underflow, leading to a
heap-based buffer over-read, in the Exiv2::IptcData::printStructure function in
iptc.cpp. Remote attackers can exploit this vulnerability to cause a denial of
service via a crafted TIFF file or, possibly, disclose memory data.
