Summary

tcpflow through 1.6.1 contains an out-of-bounds read vulnerability that allows unauthenticated attackers to read process memory by sending packets with forged IP payload lengths. Crafted IPv4 or IPv6 TCP packets injected into captured traffic or pcap files can leak adjacent memory into reconstructed flow files or crash tcpflow.

Risk Assessment

This can lead to leakage of sensitive process memory into output files or to crashes of the tool during traffic analysis.

Recommendation

Update tcpflow to a version later than 1.6.1 or apply the vendor patch; be cautious when analyzing untrusted pcap files.
