Technical details
A buffer overflow vulnerability exists in tcpdump versions prior to 4.9.0 within the Q.933 (Frame Relay) protocol parser. The flaw is located in the q933_print() function in print-fr.c and is distinct from CVE-2016-8575. An unauthenticated remote attacker can exploit this by sending specially crafted network packets or providing a malicious pcap file for analysis. Successful exploitation can result in a denial of service (application crash) or potentially arbitrary code execution with the privileges of the tcpdump process. The issue is resolved in version 4.9.0.
