F5 Networks BIG-IP : tcpdump vulnerabilities (K55129614)

High Nessus Plugin ID 104261

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 5.9


The remote device is missing a vendor-supplied security patch.



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

CVE-2016-7986 The GeoNetworking parser in tcpdump before 4.9.0 has a buffer overflow in print-geonet.c, multiple functions.

CVE-2017-5341 The OTV parser in tcpdump before 4.9.0 has a buffer overflow in print-otv.c:otv_print().


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 where tcpdump is actively capturing network traffic. The tcpdump 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.


Upgrade to one of the non-vulnerable versions listed in the F5 Solution K55129614.
