Debian DLA-3578-1 : lldpd - LTS security update

critical Nessus Plugin ID 181818

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the lldpd packages.

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