Description
In libexif through 0.6.25, an integer underflow in size checking for Fuji and Olympus MakerNote decoding could be used by attackers to crash or leak information out of libexif-using programs.
Analysis
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.
