Security update for opencv (important)

This update for opencv fixes the following issues:

Security issues fixed:

• CVE-2016-1516: OpenCV had a double free issue that allowed attackers to
  execute arbitrary code. (boo#1033152)
• CVE-2017-14136: OpenCV had an out-of-bounds write error in the function
  FillColorRow1 in utils.cpp when reading an image file by using
  cv::imread. NOTE: this vulnerability exists because of an incomplete fix
  for CVE-2017-12597. (boo#1057146)
• CVE-2017-12606: OpenCV had an out-of-bounds write error in the function
  FillColorRow4 in utils.cpp when reading an image file by using
  cv::imread. (boo#1052451)
• CVE-2017-12604: OpenCV had an out-of-bounds write error in the
  FillUniColor function in utils.cpp when reading an image file by using
  cv::imread. (boo#1052454)
• CVE-2017-12603: OpenCV had 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. (boo#1052455)
• CVE-2017-12602: OpenCV had a denial of service (memory consumption)
  issue, as demonstrated by the 10-opencv-dos-memory-exhaust test case.
  (boo#1052456)
• CVE-2017-12601: OpenCV had 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. (boo#1052457)
• CVE-2017-12600: OpenCV had a denial of service (CPU consumption) issue,
  as demonstrated by the 11-opencv-dos-cpu-exhaust test case. (boo#1052459)
• CVE-2017-12599: OpenCV had an out-of-bounds read error in the function
  icvCvt_BGRA2BGR_8u_C4C3R when reading an image file by using cv::imread.
  (boo#1052461)
• CVE-2017-12598: OpenCV had 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. (boo#1052462)
• CVE-2017-12597: OpenCV had an out-of-bounds write error in the function
  FillColorRow1 in utils.cpp when reading an image file by using
  cv::imread. (boo#1052465)
• CVE-2017-12864: 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. (boo#1054019)
• CVE-2017-12863: 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. (boo#1054020)
• CVE-2017-12862: 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. (boo#1054021)
• CVE-2017-12605: OpenCV had an out-of-bounds write error in the
  FillColorRow8 function in utils.cpp when reading an image file by using
  cv::imread. (boo#1054984)
