The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0256 advisory.

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

    CVE-2020-27827:
    A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to     be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service.
    The highest threat from this vulnerability is to system availability.

    CVE-2021-43612:
    In lldpd before 1.0.13, when decoding SONMP packets in the sonmp_decode function, it's possible to trigger     an out-of-bounds heap read via short SONMP packets.

    CVE-2023-41910:
    An issue was discovered in lldpd before 1.0.17. By crafting a CDP PDU packet with specific     CDP_TLV_ADDRESSES TLVs, a malicious actor can remotely force the lldpd daemon to perform an out-of-bounds     read on heap memory. This occurs in cdp_decode in daemon/protocols/cdp.c.

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In lldpd before 1.0.13, when decoding SONMP packets in the sonmp_decode function, it's possible to trigger     an out-of-bounds heap read via short SONMP packets. (CVE-2021-43612)

Note that Nessus relies on the presence of the package as reported by the vendor.
