This update for opencv fixes the following issues :

  - CVE-2018-5268: Fixed a heap-based buffer overflow in     incv::Jpeg2KDecoder::readComponent8u in     modules/imgcodecs/src/grfmt_jpeg2000.cppwhen parsing a     crafted image file. (boo#1075017)

  - CVE-2017-17760: Fixed an buffer overflow in function     cv::PxMDecoder::readData (boo#1074313)

  - CVE-2017-18009: Fixed a heap-based buffer over-read in     function cv::HdrDecoder::checkSignature (boo#1074312)

  - CVE-2017-1000450: Functions FillUniColor and FillUniGray     do not check the input length which could lead to out of     bounds writes and crashes (boo#1074487)

  - CVE-2018-5269: Fixed an assertion failure happens in     cv::RBaseStream::setPos     inmodules/imgcodecs/src/bitstrm.cpp because of an     incorrect integer cast (bsc#1075019).

Early versions of opencv have problems while reading data, which might result in either buffer overflows, out-of bounds errors or integer overflows.

Further assertion errors might happen due to incorrect integer cast.

For Debian 8 'Jessie', these problems have been fixed in version 2.4.9.1+dfsg-1+deb8u2.

We recommend that you upgrade your opencv packages.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2799 advisory.

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

  - 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 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 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)

  - OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the function     FillColorRow4 in utils.cpp when reading an image file by using cv::imread. (CVE-2017-12606)

  - In modules/imgcodecs/src/grfmt_pxm.cpp, the length of buffer AutoBuffer _src is small than expected, which     will cause copy buffer overflow later. If the image is from remote, may lead to remote code execution or     denial of service. This affects Opencv 3.3 and earlier. (CVE-2017-12862)

  - In opencv/modules/imgcodecs/src/grfmt_pxm.cpp, function PxMDecoder::readData has an integer overflow when     calculate src_pitch. If the image is from remote, may lead to remote code execution or denial of service.
    This affects Opencv 3.3 and earlier. (CVE-2017-12863)

  - In opencv/modules/imgcodecs/src/grfmt_pxm.cpp, function ReadNumber did not checkout the input length,     which 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-2017-12864)

  - OpenCV 3.3.1 has a Buffer Overflow in the cv::PxMDecoder::readData function in grfmt_pxm.cpp, because an     incorrect size value is used. (CVE-2017-17760)

  - 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 4.1.1. There is a NULL pointer dereference in the function     cv::XMLParser::parse at modules/core/src/persistence.cpp. (CVE-2019-14493)

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Opencv 3.3 and earlier has problems while reading data, which might result in either buffer overflows or integer overflows.

For Debian 7 'Wheezy', these problems have been fixed in version 2.3.1-11+deb7u3.

We recommend that you upgrade your opencv packages.
