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.

A flaw was found in Exiv2 0.26. The CiffDirectory::readDirectory() function at crwimageint.cpp has an excessive stack consumption due to a recursive function, leading to Denial of service.

A stack exhaustion issue in the printIFDStructure function of Exiv2 0.27 allows remote attackers to cause a denial of service (DOS) via a crafted file.
