Integer underflow in libexif version 0.6.25 and earlier during Fuji and Olympus MakerNote decoding allows local attackers to crash applications or leak sensitive memory information. The vulnerability requires local access and specific user interaction (high complexity) but affects all applications linking libexif, creating a supply-chain exposure for image processing tools.
Integer overflow in libexif through 0.6.25 Nikon MakerNote handling allows local attackers on 32-bit systems to trigger crashes or read sensitive memory, requiring high attack complexity and no user interaction. This affects only 32-bit architectures due to the integer arithmetic involved; EPSS probability is low given the local-only attack vector and high complexity prerequisite, but patch availability is currently unconfirmed.
NULL Pointer Deference in the exif command line tool, when printing out XML formatted EXIF data, in exif v0.6.22 and earlier allows attackers to cause a Denial of Service (DoS) by uploading a. Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Public exploit code available.
