Matteo Memelli reported an out-of-bounds read flaw when parsing CDP addresses in lldpd, an implementation of the IEEE 802.1ab (LLDP) protocol. A remote attacker can take advantage of this flaw to cause a denial of service via a specially crafted CDP PDU packet. . - ------------------------------------------------------------------------- Debian Security Advisory DSA-5505-1
Matteo Memelli discovered a flaw in lldpd, an implementation of the IEEE 802.1ab protocol. 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. . ------------------------------------------------------------------------- Debian LTS Advisory DLA-3578-1

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. . - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3388-1
The package lldpd before version 1.0.8-1 is vulnerable to information disclosure. . Arch Linux Security Advisory ASA-202101-29 ========================================= Severity: Medium Date : 2021-01-20 CVE-ID : CVE-2020-27827 Package : lldpd Type : information disclosure Remote : Yes Link : https://security.archlinux.org/AVG-1451 Summary ====== The package lldpd before version 1.0.8-1 is vulnerable to information disclosure. Resolution ========= Upgrade to 1.0.8-1. # pacman -Syu "lldpd> =1.0.8-1" The problem has been fixed upstream in version 1.0.8. Workaround ========= None. Description ========== A security issue was found in lldpd before version 1.0.8. A packet that contains multiple instances of certain TLVs will cause lldpd to continually allocate memory and leak the old memory. As an example, multiple instances of system name TLV will cause old values to be dropped by the decoding routine. Impact ===== A remote attack can leak information through crafted packets.
