CVE-2017-12997

Name of the Vulnerable Software and Affected Versions tcpdump versions prior to 4.9.2

Description The issue is related to a bug in the LLDP parser, which could cause an infinite loop due to a problem in the lldp private 8021 print() function. This could potentially allow a remote attacker to obtain sensitive information by sending a specially crafted request, exploiting a buffer overread memory issue in the HNCP component.

Recommendations For versions prior to 4.9.2, update to version 4.9.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the LLDP parser or the HNCP component to minimize the risk of exploitation.
