A flaw was found in multiple versions of Open vSwitch. 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.

A buffer overflow was found in the lldpdecode function in daemon/protocols/lldp.c in lldpd. This flaw allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries. This threatens the system's confidentiality, integrity, and availability.
