Integer underflow in libexif 0.6.25 and earlier allows local attackers to overwrite memory via crafted MakerNote EXIF data in image files. The flaw occurs when exif_mnote_data_get_value receives a zero-size parameter, triggering a buffer overflow that can lead to arbitrary code execution or information disclosure. No active exploitation confirmed (CISA KEV absent), but upstream commit 7df372e exists. EPSS score of 0.01% suggests low widespread exploitation likelihood, though the high-complexity local attack vector (CVSS AV:L/AC:H) limits real-world risk to scenarios where attackers control image file inputs processed by affected applications.
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.
