An issue was discovered in Exiv2 0.27. There is infinite recursion at Exiv2::Image::printTiffStructure in the file image.cpp. This can be triggered by a crafted file. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.
Weakness
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
