Libtiff is a library for reading and writing Tagged Image File Format (abbreviated TIFF) files. The set also contains command line tools for processing TIFFs. It is distributed in source code and can be found as binary builds for all kinds of platforms. The libtiff software was written by Sam Leffler while working for Silicon Graphics.
Features
Support for BigTIFF files larger than 4 GiB (4,294,967,296 bytes) was included for Libtiff 4.0.
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.[1][2][3] Some of these have also been used to execute unsigned code on the PlayStation Portable,[4] as well as run third-party applications on the iPhone and iPod Touch firmware.[5]
Website controversy
The primary libtiff website (libtiff.org) is considered hijacked.[6] While it now contains a mirror of the real site for current development, the libtiff.org site has not been updated since version 3.6.1. Because of this, much of the information contained therein is incorrect, including the current version number, authors, mailing list address, and the CVS information.
