Name of the Vulnerable Software and Affected Versions tcpdump versions prior to 4.9.2
Description The issue is related to several protocol parsers in tcpdump that could cause a buffer overflow in the bittok2str internal() function. Additionally, a buffer overread memory issue in the HNCP component could allow a remote attacker to obtain sensitive information by sending a specially crafted request.
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 HNCP component to minimize the risk of exploitation.
