• CVE-2019-19624Dec 6, 2019
  affected < 4.1.0.25fixed 4.1.0.25

  An out-of-bounds read was discovered in OpenCV before 4.1.1. 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 a

• CVE-2019-9423Sep 27, 2019
  affected <= 4.1.1.26

  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. Product: AndroidVersions:

  affected < 3.4.1.15fixed 3.4.1.15

  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.

• CVE-2018-5268Jan 8, 2018
  affected < 3.4.1.15fixed 3.4.1.15

  affected < 3.3.1.11fixed 3.3.1.11

  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.

• CVE-2017-18009Jan 1, 2018
  affected < 3.4.1.15fixed 3.4.1.15
