Summary
It was discovered that OpenCV did not properly manage certain
objects, leading to a divide-by-zero. If a user were tricked into
loading a specially crafted file, a remote attacker could potentially use
this issue to cause a denial of service or possibly execute arbitrary
code. (CVE-2019-15939)
It was discovered that OpenCV did not properly manage certain files,
leading to an out of bounds read. If a user were tricked into loading
a specially crafted file, a remote attacker could potentially use this
issue to make OpenCV crash, resulting in a denial of service. This issue
was only fixed in Ubuntu 18.04 ESM. (CVE-2019-14491, CVE-2019-14492)
It was discovered that OpenCV did not properly manage certain XML data,
leading to a NULL pointer dereference. If a user were tricked into
loading a specially crafted file, a remote attacker could potentially use
this issue to make OpenCV crash, resulting in a denial of service. This
issue was only fixed in Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.
(CVE-2019-14493)
It was discovered that OpenCV did not properly manage certain files,
leading to a heap-based buffer overflow. If a user were tricked into
loading a specially crafted file, a remote attacker could potentially use
this issue to cause a denial of service or possibly execute arbitrary code.
This issue only affected Ubuntu 18.04 ESM. (CVE-2017-18009)

Vulnerabilities 5
-
High 8.2
Out-of-bounds Read in OpenCV
An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1. 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.
-
High 7.5
Out-of-bounds Read in OpenCV
In OpenCV 3.3.1, a heap-based buffer over-read exists in the function cv::HdrDecoder::checkSignature in modules/imgcodecs/src/grfmt_hdr.cpp.
-
High 7.5
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. 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.
-
High 7.5
