opencv vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in OpenCV.

Software Description:
- opencv: computer vision library

Details:

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)
