opencv-python versions before v4.8.1.78 bundled libwebp binaries in wheels that are vulnerable to CVE-2023-4863. opencv-python v4.8.1.78 upgrades the bundled libwebp binary to v1.3.2.
In OpenCV, an assertion failure happens in cv::RBaseStream::setPos in modules/imgcodecs/src/bitstrm.cpp because of an incorrect integer cast.
OpenCV (Open Source Computer Vision Library) has 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.
OpenCV (Open Source Computer Vision Library) has an out-of-bounds write error in the FillUniColor function in utils.cpp when reading an image file by using cv::imread.
OpenCV (Open Source Computer Vision Library) has an out-of-bounds write error in the FillColorRow8 function in utils.cpp when reading an image file by using cv::imread.
In opencv calls that use libpng, there is a possible out-of-bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges required. User interaction is not required for exploitation.

An issue was discovered in OpenCV 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.
An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV A specially crafted XML file can cause a buffer overflow, resulting in multiple heap corruptions and potential code execution. An attacker can provide a specially crafted file to trigger this vulnerability.
OpenCV (Open Source Computer Vision Library) has an out-of-bounds write error in the function FillColorRow4 in utils.cpp when reading an image file by using cv::imread.
An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV, A specially crafted JSON file can cause a buffer overflow, resulting in multiple heap corruptions and potentially code execution. An attacker can provide a specially crafted file to trigger this vulnerability.
OpenCV (Open Source Computer Vision Library) 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.
In OpenCV, a heap-based buffer overflow happens in cv::Jpeg2KDecoder::readComponent8u in modules/imgcodecs/src/grfmt_jpeg2000.cpp when parsing a crafted image file.
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.
OpenCV (Open Source Computer Vision Library) has an out-of-bounds write error in the function FillColorRow1 in utils.cpp when reading an image file by using cv::imread.
OpenCV (Open Source Computer Vision Library) 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.
An issue was discovered in OpenCV There is an out-of-bounds read in the function cv::predictOrderedcv::HaarEvaluator in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.
In OpenCV, a heap-based buffer over-read exists in the function cv::HdrDecoder::checkSignature in modules/imgcodecs/src/grfmt_hdr.cpp.
OpenCV (Open Source Computer Vision Library) has an out-of-bounds read error in the function icvCvt_BGRA2BGR_8u_C4C3R when reading an image file by using cv::imread.
An out-of-bounds read was discovered in OpenCV Specifically, variable coarsest_scale is assumed to be greater than or equal to finest_scale within the calc()/ocl_calc() functions in dis_flow.cpp. However, this is not true when dealing with small images, leading to an out-of-bounds read of the heap-allocated arrays Ux and Uy.
OpenCV 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 There is a NULL pointer dereference in the function cv::XMLParser::parse at modules/core/src/persistence.cpp.
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.
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.
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.
OpenCV has a Buffer Overflow in the cv::PxMDecoder::readData function in grfmt_pxm.cpp, because an incorrect size value is used.
OpenCV allows remote attackers to cause a denial of service (segfault) via vectors involving corrupt chunks.
OpenCV has a double free issue that allows attackers to execute arbitrary code.
An issue was discovered in OpenCV There is a divide-by-zero error in cv::HOGDescriptor::getDescriptorSize in modules/objdetect/src/hog.cpp.
OpenCV (Open Source Computer Vision Library) has a denial of service (memory consumption) issue, as demonstrated by the test case.
