    Multiple file parsing vulnerabilities have been fixed in libraw. They are
    concerned with the dng and x3f formats.

    CVE-2020-35530

        There is an out-of-bounds write vulnerability within the new_node()
        function (src/x3f/x3f_utils_patched.cpp) that can be triggered via a
        crafted X3F file. Reported by github user 0xfoxone.

    CVE-2020-35531

        An out-of-bounds read vulnerability exists within the
        get_huffman_diff() function (src/x3f/x3f_utils_patched.cpp) when
        reading data from an image file. Reported by github user GirlElecta.

    CVE-2020-35532

        An out-of-bounds read vulnerability exists within the
        simple_decode_row() function (src/x3f/x3f_utils_patched.cpp) which
        can be triggered via an image with a large row_stride field.
        Reported by github user GirlElecta.

    CVE-2020-35533

        An out-of-bounds read vulnerability exists within the
        LibRaw::adobe_copy_pixel() function (src/decoders/dng.cpp) when
        reading data from the image file. Reported by github user GirlElecta.

    For Debian 10 buster, these problems have been fixed in version
    0.19.2-2+deb10u1.

    We recommend that you upgrade your libraw packages.
