F5 Networks BIG-IP : tcpdump vulnerabilities (K94778122)

critical Nessus Plugin ID 104342

Language:

Synopsis

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

Description

CVE-2016-7985

The CALM FAST parser in tcpdump before 4.9.0 has a buffer overflow in print-calm-fast.c:calm_fast_print().

CVE-2016-7992 The Classical IP over ATM parser in tcpdump before 4.9.0 has a buffer overflow in print-cip.c:cip_if_print().

CVE-2016-7993 A bug in util-print.c:relts_print() in tcpdump before 4.9.0 could cause a buffer overflow in multiple protocol parsers (DNS, DVMRP, HSRP, IGMP, lightweight resolver protocol, PIM).

CVE-2016-8574 The FRF.15 parser in tcpdump before 4.9.0 has a buffer overflow in print-fr.c:frf15_print().

CVE-2016-8575 The Q.933 parser in tcpdump before 4.9.0 has a buffer overflow in print-fr.c:q933_print(), a different vulnerability than CVE-2017-5482.

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 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.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K94778122.
