"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0011 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-44429:
    A heap-based buffer overflow vulnerability was found in GStreamer in the AV1 codec parser when handling
    certain malformed streams. A malicious third party could use this flaw to trigger a crash in the
    application and possibly affect code execution through heap manipulation.

    CVE-2023-44446:
    A use-after-free flaw was found in the MXF demuxer in GStreamer when handling certain MXF video files.
    This issue could allow a malicious third party to trigger a crash in the application and may allow code
    execution.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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