Double Free
OpenCV has a double free issue that allows attackers to execute arbitrary code.

Out-of-bounds Write
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.

NULL Pointer Dereference
An issue was discovered in OpenCV There is a NULL pointer dereference in the function cv::XMLParser::parse at modules/core/src/persistence.cpp.

Denial of Service in OpenCV
OpenCV (Open Source Computer Vision Library) has a denial of service (CPU consumption) issue, as demonstrated by the test case.

Out-of-bounds Write
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.

Integer Overflow or Wraparound
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.

Divide By Zero
An issue was discovered in OpenCV There is a divide-by-zero error in cv::HOGDescriptor::getDescriptorSize in modules/objdetect/src/hog.cpp.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
OpenCV (Open Source Computer Vision Library) 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.

Improper Restriction of Operations within the Bounds of a Memory Buffer
OpenCV has a Buffer Overflow in the cv::PxMDecoder::readData function in grfmt_pxm.cpp, because an incorrect size value is used.

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

Out-of-bounds Read
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.

Out-of-bounds Read
An issue was discovered in OpenCV There is an out-of-bounds read in the function cv::predictOrdered<cv::HaarEvaluator> in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.
