NVD Description

Note: Versions mentioned in the description apply only to the upstream lldpd package and not the lldpd package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

An issue was discovered in lldpd before 1.0.17. By crafting a CDP PDU packet with specific CDP_TLV_ADDRESSES TLVs, a malicious actor can remotely force the lldpd daemon to perform an out-of-bounds read on heap memory. This occurs in cdp_decode in daemon/protocols/cdp.c.
