F5F5:K94010578K94010578 : tcpdump vulnerabilities CVE-2016-7940, CVE-2016-7973, CVE-2016-7974, CVE-2016-7983, and CVE-2016-7984
Security Advisory Description
The STP parser in tcpdump before 4.9.0 has a buffer overflow in print-stp.c, multiple functions.
The AppleTalk parser in tcpdump before 4.9.0 has a buffer overflow in print-atalk.c, multiple functions.
The IP parser in tcpdump before 4.9.0 has a buffer overflow in print-ip.c, multiple functions.
The BOOTP parser in tcpdump before 4.9.0 has a buffer overflow in print-bootp.c:bootp_print().
The TFTP parser in tcpdump before 4.9.0 has a buffer overflow in print-tftp.c:tftp_print().
Impact
An attacker can gain access to sensitive information. An attacker can also cause a denial of service (DoS) via 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.
