vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - opencv: out-of-bounds write error in the function FillColorRow4 (CVE-2017-12606)

  - OpenCV 3.0.0 has a double free issue that allows attackers to execute arbitrary code. (CVE-2016-1516)

  - OpenCV 3.0.0 allows remote attackers to cause a denial of service (segfault) via vectors involving corrupt
    chunks. (CVE-2016-1517)

  - In opencv/modules/imgcodecs/src/utils.cpp, functions FillUniColor and FillUniGray do not check the input
    length, which can lead to integer overflow. If the image is from remote, may lead to remote code execution
    or denial of service. This affects Opencv 3.3 and earlier. (CVE-2017-1000450)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the function
    FillColorRow1 in utils.cpp when reading an image file by using cv::imread. (CVE-2017-12597)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds read error in the
    cv::RBaseStream::readBlock function in modules/imgcodecs/src/bitstrm.cpp when reading an image file by
    using cv::imread, as demonstrated by the 8-opencv-invalid-read-fread test case. (CVE-2017-12598)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds read error in the function
    icvCvt_BGRA2BGR_8u_C4C3R when reading an image file by using cv::imread. (CVE-2017-12599)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has a denial of service (CPU consumption) issue,
    as demonstrated by the 11-opencv-dos-cpu-exhaust test case. (CVE-2017-12600)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has a buffer overflow in the
    cv::BmpDecoder::readData function in modules/imgcodecs/src/grfmt_bmp.cpp when reading an image file by
    using cv::imread, as demonstrated by the 4-buf-overflow-readData-memcpy test case. (CVE-2017-12601)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has a denial of service (memory consumption)
    issue, as demonstrated by the 10-opencv-dos-memory-exhaust test case. (CVE-2017-12602)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has an invalid write in the
    cv::RLByteStream::getBytes function in modules/imgcodecs/src/bitstrm.cpp when reading an image file by
    using cv::imread, as demonstrated by the 2-opencv-heapoverflow-fseek test case. (CVE-2017-12603)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the
    FillUniColor function in utils.cpp when reading an image file by using cv::imread. (CVE-2017-12604)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the
    FillColorRow8 function in utils.cpp when reading an image file by using cv::imread. (CVE-2017-12605)

  - In OpenCV 3.3.1, a heap-based buffer overflow happens in cv::Jpeg2KDecoder::readComponent8u in
    modules/imgcodecs/src/grfmt_jpeg2000.cpp when parsing a crafted image file. (CVE-2018-5268)

  - In OpenCV 3.3.1, an assertion failure happens in cv::RBaseStream::setPos in
    modules/imgcodecs/src/bitstrm.cpp because of an incorrect integer cast. (CVE-2018-5269)

  - An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1. There is an out of bounds read/write
    in the function HaarEvaluator::OptFeature::calc in modules/objdetect/src/cascadedetect.hpp, which leads to
    denial of service. (CVE-2019-14492)

  - An issue was discovered in OpenCV 4.1.0. There is a divide-by-zero error in
    cv::HOGDescriptor::getDescriptorSize in modules/objdetect/src/hog.cpp. (CVE-2019-15939)
