PYSEC-2026-2814 Out-of-bounds Write in OpenCV.

In OpenCV 3.3.1 corresponding with OpenCV-Python 3.3.1.11, a heap-based buffer overflow happens in cv::Jpeg2KDecoder::readComponent8u in modules/imgcodecs/src/grfmtjpeg2000.cpp when parsing a crafted image file...

PYSEC-2026-2837 Out-of-bounds Read and Out-of-bounds Write in OpenCV

An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1 OpenCV-Python before 3.4.7.28 and 4.x before 4.1.1.26. 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...

PYSEC-2026-2810 Out-of-bounds Read in OpenCV

In OpenCV 3.3.1 corresponding with OpenCV-Python 3.3.1.11, a heap-based buffer over-read exists in the function cv::HdrDecoder::checkSignature in modules/imgcodecs/src/grfmthdr.cpp...

DEBIAN-CVE-2019-19624

An out-of-bounds read was discovered in OpenCV before 4.1.1. Specifically, variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this is not true when dealing with small images, leading to an out-of-bounds read of t...

CVE-2017-14136

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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-12597...

UBUNTU-CVE-2017-12603

OpenCV Open Source Computer Vision Library through 3.3 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...

CVE-2017-12598

CVE-2017-12598 affects OpenCV up to version 3.3.0, where an out-of-bounds read occurs in cv::RBaseStream::readBlock (modules/imgcodecs/src/bitstrm.cpp) when reading an image with cv::imread, as demonstrated by the 8-opencv-invalid-read-fread test case. The connected documents confirm the vulnerab...
