CVE-2019-14491

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 in the function cv::predictOrderedcv::HaarEvaluator in modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.

The updated packages fix security vulnerabilities:

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. (CVE-2019-14491)

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. (CVE-2019-14492)

An issue was discovered in OpenCV 4.1.0. There is a divide-by-zero error in cv::HOGDescriptor::getDescriptorSize in modules/objdetect/src/hog.cpp. (CVE-2019-15939)

This update for opencv fixes the following issues:

Security issues fixed:

• CVE-2019-14491: Fixed an out of bounds read in the function cv:predictOrderedcv:HaarEvaluator, leading to DOS (bsc#1144352).
• CVE-2019-14492: Fixed an out of bounds read/write in the function HaarEvaluator:OptFeature:calc, which leads to denial of service (bsc#1144348).
• CVE-2019-15939: Fixed a divide-by-zero error in cv:HOGDescriptor:getDescriptorSize (bsc#1149742).

Non-security issue fixed:

• Fixed an issue in opencv-devel that broke builds with 'No rule to make target opencv_calib3d-NOTFOUND' (bsc#1154091).

This update was imported from the SUSE:SLE-15:Update update project.

These are all security issues fixed in the libopencv4_5-4.5.2-2.2 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libopencv3_4-3.4.10-3.3 package on the GA media of openSUSE Tumbleweed.

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)
