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.
