There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Buffer Overflow vulnerability in libde265 v1.0.12 allows a local attacker to cause a denial of service via
    the allocation size exceeding the maximum supported size of 0x10000000000. (CVE-2023-51792)

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6764-1 advisory.

    It was discovered that libde265 could be made to allocate memory that exceeds the maximum supported size.
    If a user or automated system were tricked into opening a specially crafted file, an attacker could     possibly use this issue to cause a denial of service.

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

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

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4550 advisory.

    It was found that libde265, an open source implementation of the H.265 video     codec, had multiple vulnerabilities which could lead to both stack and heap     out of bound writes that could lead to denial of service, etc.

    For Debian 11 bullseye, these problems have been fixed in version     1.0.11-0+deb11u4.

    We recommend that you upgrade your libde265 packages.
