Description Sam Fowler 2018-01-21 20:51:22 EST 
In Exiv2 0.26, there is a segmentation fault caused by uncontrolled recursion in the Exiv2::Image::printIFDStructure function in the image.cpp file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tif file.
