opencv-contrib-python-headless versions before v4.8.1.78 bundled libwebp binaries in wheels that are vulnerable to CVE-2023-4863. opencv-contrib-python-headless v4.8.1.78 upgrades the bundled libwebp binary to v1.3.2.
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.
An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV, before version 4.2.0. 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.
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 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 an out-of-bounds read in the function cv::predictOrderedcv::HaarEvaluator in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.
An issue was discovered in OpenCV There is a NULL pointer dereference in the function cv::XMLParser::parse at modules/core/src/persistence.cpp.
An issue was discovered in OpenCV There is a divide-by-zero error in cv::HOGDescriptor::getDescriptorSize in modules/objdetect/src/hog.cpp.
