Security Advisory Description

The TCP parser in tcpdump before 4.9.0 has a buffer overflow in print-tcp.c:tcp_print().

The GeoNetworking parser in tcpdump before 4.9.0 has a buffer overflow in print-geonet.c, multiple functions.

The OTV parser in tcpdump before 4.9.0 has a buffer overflow in print-otv.c:otv_print().

Impact

An attacker can gain access to sensitive information. An attacker can also cause a denial of service (DoS) by way of a crafted pcap file or by sending specially crafted packets to the network segment wheretcpdump is actively capturing network traffic. Thetcpdump program does not use the protocol decoding subsystem, and is, therefore, not affected by these vulnerabilities when using the-w option to write raw packets to a** pcap** file for offline examination.
