Security Advisory Description

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

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

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).

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

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 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.
