CVE-2015-8011Network attack vector

Daemon crash via oversized management-address TLV

Published Jan 28, 2020 · Updated Aug 6, 2024

Buffer overflow in lldpd 0.6.0 through 0.7.18 allows remote attackers on the local network to crash the daemon with a crafted LLDP packet. The lldp_decode management-address TLV path trusts its one-byte address length and copies that many bytes into a smaller fixed static buffer. No authentication or user interaction is required, but the parser is unprivileged and chrooted, so code execution requires disabled hardening.
