    attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the
    victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the
    interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra
    command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5. (CVE-2021-37615,
    CVE-2021-37616)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata
    of image files. An out-of-bounds read was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds
    read is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could
    potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into
    running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the image ICC
    profile, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p
    C`). The bug is fixed in version v0.27.5. (CVE-2021-37618)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata
    of image files. An out-of-bounds read was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds
    read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could
    potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick
    the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing
    the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to
    trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such
    as insert. The bug is fixed in version v0.27.5. (CVE-2021-37619)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata
    of image files. An infinite loop was found in Exiv2 versions v0.27.4 and earlier. The infinite loop is
    triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially
    exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on
    a crafted image file. Note that this bug is only triggered when printing the image ICC profile, which is a

    exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on
    a crafted image file. Note that this bug is only triggered when deleting the IPTC data, which is a less
    frequently used Exiv2 operation that requires an extra command line option (`-d I rm`). The bug is fixed
    in version v0.27.5. (CVE-2021-37622, CVE-2021-37623)
