Exploits
A TIFF file is composed of small descriptor blocks containing offsets into the file which point to a variety of data types. Incorrect offset values can cause programs to attempt to read erroneous portions of the file or attempt to read past the physical end of file. Improperly encoded packet or line lengths within the file can cause rendering programs which lack appropriate boundary checks to overflow their internal buffers.
Multiple buffer overflows have been found in Libtiff. Some of these have also been used to execute unsigned code on the PlayStation Portable, as well as run third-party applications on the iPhone and iPod Touch firmware.
