    Three security vulnerabilities were discovered in libexif, a library to reads     and writes EXIF metainformation from and to images files, that can causes     crashes or information leaks.

    CVE-2026-32775

        If the exif_mnote_data_get_value function in MakerNotes gets passed         in a 0 size, the passed in-buffer would be overwritten due to an         integer underflow.

    CVE-2026-40385

        An unsigned 32bit integer overflow in Nikon MakerNote handling could         be used by local attackers to cause crashes or information leaks.

    CVE-2026-40386

        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.

    For Debian 11 bullseye, these problems have been fixed in version     0.6.22-3+deb11u1.

    We recommend that you upgrade your libexif packages.
