CVE-2026-119600tcpflow < 1.7.0 Out-of-Bounds Read via TCP Demultiplexer Payload Length

Beschreibung

tcpflow before 1.7.0 contains an out-of-bounds read vulnerability that allows unauthenticated attackers to read process memory by sending packets with forged IP payload lengths. Attackers can inject crafted IPv4 or IPv6 TCP packets into captured traffic or pcap files to leak adjacent memory into reconstructed flow files or crash tcpflow.
