Vulnerabilities

OpenCV is an Open Source Computer Vision Library.

A vulnerability, which was classified as problematic, has been found in OpenCV wechat_qrcode Module up to 4.7.0.

A vulnerability classified as problematic was found in OpenCV wechat_qrcode Module up to 4.7.0.

An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV, before version 4.2.0.

An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV 4.1.0.

An out-of-bounds read was discovered in OpenCV before 4.1.1.

OpenCV 4.1.1 has an out-of-bounds read in hal_baseline::v_load in core/hal/intrin_sse.hpp when called from computeSSDMeanNorm in modules/video/src/dis_flow.cpp.

An issue was discovered in OpenCV 4.1.0.

An issue was discovered in OpenCV before 4.1.1.

An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1.

An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1.

The validateInputImageSize function in modules/imgcodecs/src/loadsave.cpp in OpenCV 3.4.1 allows remote attackers to cause a denial of service (assertion failure) because (pixels <= (1<<30)) may be false.

The validateInputImageSize function in modules/imgcodecs/src/loadsave.cpp in OpenCV 3.4.1 allows remote attackers to cause a denial of service (assertion failure) because (size.width <= (1<<20)) may be false.

The validateInputImageSize function in modules/imgcodecs/src/loadsave.cpp in OpenCV 3.4.1 allows remote attackers to cause a denial of service (assertion failure) because (size.height <= (1<<20)) may be false.

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.

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.

In opencv/modules/imgcodecs/src/utils.cpp, functions FillUniColor and FillUniGray do not check the input length, which can lead to integer overflow.

In OpenCV 3.3.1, a heap-based buffer over-read exists in the function cv::HdrDecoder::checkSignature in modules/imgcodecs/src/grfmt_hdr.cpp.

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.

OpenCV (Open Source Computer Vision Library) 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.

In opencv/modules/imgcodecs/src/grfmt_pxm.cpp, function ReadNumber did not checkout the input length, which lead to integer overflow.

In opencv/modules/imgcodecs/src/grfmt_pxm.cpp, function PxMDecoder::readData has an integer overflow when calculate src_pitch.

In modules/imgcodecs/src/grfmt_pxm.cpp, the length of buffer AutoBuffer _src is small than expected, which will cause copy buffer overflow later.

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.

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.
