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. Note: “OpenCV CV_Assert is not an assertion (C-like assert()), it is regular C++ exception which can raised in case of invalid or non-supported parameters. ** EN DISPUTA ** La función validateInputImageSize en modules/imgcodecs/src/loadsave.cpp en OpenCV versión 3.4.1 permite a los atacantes remotos causar una denegación de servicio (assertion failure) porque (size.height menor= (1 menor 20)) puede ser falso Nota: "OpenCV CV_Assert no es una aserción (C-like assert()), es una excepción normal de C ++ que se puede generar en caso de parámetros no válidos o no admitidos". • https://github.com/opencv/opencv/issues/10998 https://github.com/xiaoqx/pocs/tree/master/opencv/dos-by-assert • CWE-617: Reachable Assertion •

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. En OpenCV 3.3.1, ocurre un fallo de aserción en cv::RBaseStream::setPos en modules/imgcodecs/src/bitstrm.cpp debido a un pase de enteros incorrecto. • http://www.securityfocus.com/bid/106945 https://github.com/opencv/opencv/issues/10540 https://lists.debian.org/debian-lts-announce/2018/04/msg00019.html https://lists.debian.org/debian-lts-announce/2018/07/msg00030.html https://lists.debian.org/debian-lts-announce/2021/10/msg00028.html • CWE-617: Reachable Assertion •

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. En OpenCV 3.3.1, ocurre un desbordamiento de búfer basado en memoria dinámica (heap) en cv::Jpeg2KDecoder::readComponent8u en modules/imgcodecs/src/grfmt_jpeg2000.cpp al analizar un archivo de imagen manipulado. • http://www.securityfocus.com/bid/106945 https://github.com/opencv/opencv/issues/10541 https://lists.debian.org/debian-lts-announce/2018/04/msg00019.html https://lists.debian.org/debian-lts-announce/2018/07/msg00030.html https://lists.debian.org/debian-lts-announce/2021/10/msg00028.html • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2017-1000450
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 3.3 and earlier. En opencv/modules/imgcodecs/src/utils.cpp, las funciones FillUniColor y FillUniGray no comprueban la longitud de la entrada, lo que puede conducir a un desbordamiento de enteros. Si la imagen proviene de una fuente remota, podría provocar la ejecución remota de código o una denegación de servicio. • https://github.com/blendin/pocs/blob/master/opencv/0.OOB_Write_FillUniColor https://github.com/opencv/opencv/issues/9723 https://lists.debian.org/debian-lts-announce/2018/01/msg00008.html https://lists.debian.org/debian-lts-announce/2018/07/msg00030.html https://lists.debian.org/debian-lts-announce/2021/10/msg00028.html • CWE-190: Integer Overflow or Wraparound •
