The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3578 advisory.

  • 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. (CVE-2023-41910)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
