- 漏洞讨论

By design, tcpdump on Red Hat Linux should lower its privileges from root to user pcap after it has begun reading from an interface. Due to a compilation error, this did not correctly occur unless manually specified at runtime with a command-line parameter. As a result tcpdump may run on systems with root privileges when administrators assume they've been dropped.

- 漏洞利用

There is no exploit code required.
