    It was discovered that there were two potential denial of service     (DoS) attacks in lldpd, a implementation of the IEEE 802.1ab (LLDP)     protocol used to administer and monitor networking devices.

    For Debian 10 buster, these problems have been fixed in version     1.0.3-1+deb10u1.

    We recommend that you upgrade your lldpd packages.

    For the detailed security status of lldpd please refer to     its security tracker page at:

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0343 advisory.

    Package updates are available for TencentOS Server 4 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.
