Background
exiv2 is an open-source library and command-line utility for managing image metadata. It provides functionality to read, write, and modify metadata in various image file formats. The library is widely used in applications that deal with image processing and management. However, a vulnerability has been discovered in exiv2 that allows an attacker to cause a denial of service by exploiting crafted TIFF images.
