CVE-2017-12956

There is an illegal address access in Exiv2::FileIo::path[abi:cxx11]() in basicio.cpp of libexiv2 in Exiv2 0.26 that will lead to remote denial of service.

CVE-2017-12957

There is a heap-based buffer over-read in libexiv2 in Exiv2 0.26 that is triggered in the Exiv2::Image::io function in image.cpp. It will lead to remote denial of service.
