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.
