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

    -------------------------------------------------------------------------     Debian LTS Advisory DLA-3578-1                debian-lts@lists.debian.org     https://www.debian.org/lts/security/                      Markus Koschany     September 22, 2023                            https://wiki.debian.org/LTS

    Package        : lldpd     Version        : 1.0.3-1+deb10u2     CVE ID         : CVE-2023-41910

    Matteo Memelli discovered a flaw in lldpd, an implementation of the IEEE     802.1ab protocol. 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.

    For Debian 10 buster, this problem has been fixed in version     1.0.3-1+deb10u2.

    We recommend that you upgrade your lldpd packages.

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

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

The version of lldpd installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-41910 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.

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

  - 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 relies on the presence of the package as reported by the vendor.

The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5505 advisory.

    Matteo Memelli reported an out-of-bounds read flaw when parsing CDP addresses in lldpd, an implementation     of the IEEE 802.1ab (LLDP) protocol. A remote attacker can take advantage of this flaw to cause a denial     of service via a specially crafted CDP PDU packet. For the oldstable distribution (bullseye), this problem     has been fixed in version 1.0.11-1+deb11u2. For the stable distribution (bookworm), this problem has been     fixed in version 1.0.16-1+deb12u1. We recommend that you upgrade your lldpd packages. For the detailed     security status of lldpd please refer to its security tracker page at: \https://security-     tracker.debian.org/tracker/lldpd

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:9158 advisory.

    LLDP is an industry standard protocol designed to supplant proprietary Link-Layer protocols such as EDP or     CDP. The goal of LLDP is to provide an inter-vendor compatible mechanism to deliver Link-Layer     notifications to adjacent network devices.

    Security Fix(es):

    * lldp/openvswitch: denial of service via externally triggered memory leak (CVE-2020-27827)

    * lldpd: out-of-bounds read when decoding SONMP packets (CVE-2021-43612)

    * lldpd: CDP PDU Packet cdp.c out-of-bounds read (CVE-2023-41910)
