Package : lldpd Version : 1.0.3-1+deb10u1 CVE IDs : CVE-2020-27827 CVE-2021-43612 Debian Bug : 980132

* The following was previously incorrectly announced to this list *
* as DLA-3388-1. The correct DLA identifier for this advisory is *
* DLA-3389-1. *

It was discovered that there were two potential denial of service (DoS) attacks in lldpd, a implementation of the IEEE 802.1ab (LLDP) protocol used to administer and monitor networking devices.

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

We recommend that you upgrade your lldpd packages.

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