Description Aleksandr Wagner (Kivak) 2017-08-19 07:26:41 UTC 
CVE-2017-12955 (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-12955):

There is a heap-based buffer overflow in basicio.cpp of Exiv2 0.26. The vulnerability causes an out-of-bounds write in Exiv2::Image::printIFDStructure(), which may lead to remote denial of service or possibly unspecified other impact.
