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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4818-1 advisory.

    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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for opencv fixes the following issues :

Security issues fixed :

CVE-2019-14491: Fixed an out of bounds read in the function cv:predictOrdered<cv: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).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
