CVE-2015-8011

CVSS v3.1

9.8

Critical

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions lldpd versions prior to 0.8.0
Description The issue is related to a buffer overflow in the lldp decode function, which can be exploited by remote attackers to cause a denial of service, potentially leading to a daemon crash, and possibly execute arbitrary code. This can be achieved through vectors involving large management addresses and TLV boundaries. The vulnerability allows an attacker to access confidential data, compromise its integrity, and cause a service disruption.
Recommendations For versions prior to 0.8.0, update to version 0.8.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the lldp decode function in the daemon/protocols/lldp.c component to minimize the risk of exploitation.
