Description GLSAMaker/CVETool Bot gentoo-dev 2018-02-16 01:00:25 UTC 
CVE-2017-17724 (https://nvd.nist.gov/vuln/detail/CVE-2017-17724):
  In Exiv2 0.26, there is 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.

This change is rather substantial, so that it won't make much sense anymore to backport to 0.26 branch.

    media-gfx/exiv2: Tarball respun for CVE-2017-17724
    
    Custom packed tarball based on upstream 0.26 branch as of 2018-08-11,
    with additional fixes from git master.
    
    Ignore massive test suite changes, since we do not use it at all in 0.26.
