Name of the Vulnerable Software and Affected Versions
tcpdump versions prior to 4.9.2
Description
The issue is related to a buffer over-read in the IPv6 parser, specifically in the
ip6 print() function within print-ip6.c. This could allow a remote attacker to obtain sensitive information by sending a specially crafted request. The estimated number of potentially affected devices worldwide is not specified. There is no information provided about real-world incidents where this issue was exploited.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 until a patch is available. Avoid using the
ip6 print() function in the affected print-ip6.c file until the issue is resolved.Exploit
