There is a heap-based buffer overflow in the Image::printIFDStructure function of image.cpp in Exiv2 0.26. A Crafted input will lead to a remote denial of service attack.

There is an infinite loop in the Exiv2::Image::printIFDStructure function of image.cpp in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.

There is an invalid free in the Action::TaskFactory::cleanup function of actions.cpp in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.

There is a heap-based buffer over-read in the Image::printIFDStructure function in image.cpp in Exiv2 0.26. A Crafted input will lead to a remote denial of service attack.

There is an invalid free in Image::printIFDStructure that leads to a Segmentation fault in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.

An issue was discovered in Exiv2 0.26. When the data structure of the structure ifd is incorrect, the program assigns pValue_ to 0x0, and the value of pValue() is 0x0. TiffImageEntry::doWriteImage will use the value of pValue() to cause a segmentation fault. To exploit this vulnerability, someone must open a crafted tiff file.

Integer overflow in exif.cpp in exiv2 library allows context-dependent attackers to execute arbitrary code via a crafted EXIF file that triggers a heap-based buffer overflow.
