Debian DLA-3389-1 : lldpd - LTS security update

high Nessus Plugin ID 174170

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3389 advisory.

- 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-2020-27827)

- 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-2021-43612)

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

Solution

Upgrade the lldpd packages.

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