An issue was discovered in OpenCV before 4.1.1. There is a NULL pointer dereference in the function cv::XMLParser::parse at modules/core/src/persistence.cpp.

The remote Ubuntu 18.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7247-1 advisory.

    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     possibly use this issue to make OpenCV crash, resulting in a denial of service. This issue only affected     Ubuntu 18.04 LTS. (CVE-2019-14493)

    It was discovered that OpenCV may perform out-of-bounds reads in certain situations. An attacker could     possibly use this issue to cause OpenCV to crash, resulting in a denial of service, or the execution of     arbitrary code. This issue only affected Ubuntu 18.04 LTS. (CVE-2019-16249, CVE-2019-19624)

    It was discovered that the QR code module of OpenCV incorrectly processed certain maliciously crafted QR     codes. A remote attacker could possibly use this issue to cause OpenCV to crash, resulting in a denial of     service. This issue only affected Ubuntu 22.04 LTS. (CVE-2023-2617, CVE-2023-2618)

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)

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2799 advisory.

    Several security vulnerabilities have been discovered in OpenCV, the Open Computer Vision Library. Buffer     overflows, NULL pointer dereferences and out-of-bounds write errors may lead to a denial-of-service or     other unspecified impact. For Debian 9 stretch, these problems have been fixed in version     2.4.9.1+dfsg1-2+deb9u1. We recommend that you upgrade your opencv packages. For the detailed security     status of opencv please refer to its security tracker page at: https://security-     tracker.debian.org/tracker/opencv Further information about Debian LTS security advisories, how to apply     these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
