  • 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.
