Description
In libexif through 0.6.25, an unsigned 32bit integer overflow in Nikon MakerNote handling could be used by local attackers to cause crashes or information leaks. This only affects 32bit systems.
Analysis
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.
