Various minor vulnerabilities have been addredd in libexif, a library to
parse EXIF metadata files.

CVE-2018-20030

    This issue had already been addressed via DLA-2214-1. However, upstream
    provided an updated patch, so this has been followed up on.

CVE-2020-13112

    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.

CVE-2020-13113

    Use of uninitialized memory in EXIF Makernote handling could have
    lead to crashes and potential use-after-free conditions.

CVE-2020-13114

    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
0.6.21-2+deb8u3.

We recommend that you upgrade your libexif packages.
