  - libraw: Out-of-bounds read in the kodak_65000_load_raw function (CVE-2017-14608)

  - LibRaw: Stack buffer overflow in LibRaw::identify_process_dng_fields() in identify.cpp (CVE-2020-24870)

  - There is a floating point exception in the kodak_radc_load_raw function in dcraw_common.cpp in LibRaw
    0.18.2. It will lead to a remote denial of service attack. (CVE-2017-13735)

  - An error related to the LibRaw::panasonic_load_raw() function (dcraw_common.cpp) in LibRaw versions
    prior to 0.18.6 can be exploited to cause a heap-based buffer overflow and subsequently cause a crash via
    a specially crafted TIFF image. (CVE-2017-16909)

  - An error within the LibRaw::xtrans_interpolate() function (internal/dcraw_common.cpp) in LibRaw versions
    prior to 0.18.6 can be exploited to cause an invalid read memory access and subsequently a Denial of
    Service condition. (CVE-2017-16910)

  - An error within the LibRaw::unpack() function (src/libraw_cxx.cpp) in LibRaw versions prior to 0.18.7
    can be exploited to trigger a NULL pointer dereference. (CVE-2018-5801)

  - An error within the kodak_radc_load_raw() function (internal/dcraw_common.cpp) related to the buf
    variable in LibRaw versions prior to 0.18.7 can be exploited to cause an out-of-bounds read memory access
    and subsequently cause a crash. (CVE-2018-5802)

  - A boundary error within the quicktake_100_load_raw() function (internal/dcraw_common.cpp) in LibRaw
    versions prior to 0.18.8 can be exploited to cause a stack-based buffer overflow and subsequently cause a
    crash. (CVE-2018-5805)

  - In LibRaw, there is an out-of-bounds write vulnerability within the new_node() function
    (libraw\src\x3f\x3f_utils_patched.cpp) that can be triggered via a crafted X3F file. (CVE-2020-35530)

  - In LibRaw, an out-of-bounds read vulnerability exists within the get_huffman_diff() function
    (libraw\src\x3f\x3f_utils_patched.cpp) when reading data from an image file. (CVE-2020-35531)

  - In LibRaw, an out-of-bounds read vulnerability exists within the simple_decode_row() function
    (libraw\src\x3f\x3f_utils_patched.cpp) which can be triggered via an image with a large row_stride field.
    (CVE-2020-35532)

  - In LibRaw, an out-of-bounds read vulnerability exists within the LibRaw::adobe_copy_pixel() function
    (libraw\src\decoders\dng.cpp) when reading data from the image file. (CVE-2020-35533)

  - In LibRaw, there is a memory corruption vulnerability within the crxFreeSubbandData() function
    (libraw\src\decoders\crx.cpp) when processing cr3 files. (CVE-2020-35534)

  - In LibRaw, there is an out-of-bounds read vulnerability within the LibRaw::parseSonySRF() function
    (libraw\src\metadata\sony.cpp) when processing srf files. (CVE-2020-35535)
