August 29, 2025

A denial-of-service was found in Exiv2 version v0.28.5: a quadratic algorithm in the ICC profile parsing code in jpegBase::readMetadata() can cause Exiv2 to run for a long time. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted jpg image file.
