"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0178 advisory.

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

    CVE-2023-45236:
    EDK2's Network Package is susceptible to a predictable TCP Initial Sequence Number. This
    vulnerability can be exploited by an attacker to gain unauthorized
    access and potentially lead to a loss of Confidentiality.

    CVE-2023-45237:
    EDK2's Network Package is susceptible to a predictable TCP Initial Sequence Number. This
    vulnerability can be exploited by an attacker to gain unauthorized
    access and potentially lead to a loss of Confidentiality.

    CVE-2024-1298:
    EDK2 contains a vulnerability when S3 sleep is activated where an Attacker may cause a Division-By-Zero
    due to a UNIT32 overflow via local access. A successful exploit of this vulnerability may lead to a loss
    of Availability.

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.");
