Background
libtiff is an open-source library for reading and writing TIFF image files. It provides support for various compression schemes and color spaces. The library is widely used in applications that deal with image processing and manipulation. However, libtiff is vulnerable to multiple buffer overflows and integer overflows, which can lead to application crashes or potentially more severe consequences.
