Description Laura Pardo 2018-04-12 17:35:42 EDT 
In Exiv2 0.26, an out-of-bounds read in IptcData::printStructure in iptc.cpp
could result in a crash or information leak, due to use of the untrusted `len`
value without any check.

Comment 1 Laura Pardo 2018-04-12 17:42:38 EDT 
Created exiv2 tracking bugs for this issue:

Affects: fedora-all [bug 1566727]
Comment 3 Riccardo Schirone 2018-04-18 09:03:33 EDT 
Statement:

This issue did not affect the versions of Exiv2 as shipped with Red Hat Enterprise Linux 6 and 7, up to 7.4, as they did not include support for printing IPTC Photo Metadata.
