Debian DSA-5505-1 : lldpd - security update

critical Nessus Plugin ID 181879

Language:

Synopsis

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

Description

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

Tenable has extracted the preceding description block directly from the Debian security advisory.

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 the stable distribution (bookworm), this problem has been fixed in version 1.0.16-1+deb12u1.
