    Various minor vulnerabilities have been addredd in libexif, a library to
    parse EXIF metadata files.
        This issue had already been addressed via DLA-2214-1. However, upstream
        provided an updated patch, so this has been followed up on.
        Several buffer over-reads in EXIF MakerNote handling could have lead
        to information disclosure and crashes. This issue is different from
        already resolved CVE-2020-0093.
        Use of uninitialized memory in EXIF Makernote handling could have
        lead to crashes and potential use-after-free conditions.
        An unrestricted size in handling Canon EXIF MakerNote data could have
        lead to consumption of large amounts of compute time for decoding
        EXIF data.
    For Debian 8 "Jessie", these problems have been fixed in version
    We recommend that you upgrade your libexif packages.
