CVE-2017-12894

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

Description The issue is related to several protocol parsers that could cause a buffer over-read in the lookup bytestring() function. This could allow a remote attacker to obtain sensitive information by sending a specially crafted request, exploiting the buffer overread memory 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 HNCP component to minimize the risk of exploitation.
