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.

Comment 6 Riccardo Schirone 2018-02-22 09:09:18 UTC

This issue did not affect the versions of Exiv2 as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for printing IPTC Photo Metadata.
