CVE-2016-7922 tcpdump vulnerabilities
Title: tcpdump vulnerabilities
Summary: tcpdump could be made to crash or run programs if it received specially
crafted network traffic.
It was discovered that tcpdump incorrectly handled certain packets. A
remote attacker could use this issue to cause tcpdump to crash, resulting
in a denial of service, or possibly execute arbitrary code.
In the default installation, attackers would be isolated by the tcpdump
AppArmor profile.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.

tcpdump: multiple overflow issues in protocol decoding
vendor_redhat·2017-02-02·CVSS 9.8
CVE-2016-7923 [CRITICAL] CWE-125 tcpdump: multiple overflow issues in protocol decoding
tcpdump: multiple overflow issues in protocol decoding
The ARP parser in tcpdump before 4.9.0 has a buffer overflow in print-arp.c:arp_print().
Multiple out of bounds read and integer overflow vulnerabilities were found in tcpdump affecting the decoding of various protocols. An attacker could create a crafted pcap file or send specially crafted packets to the network segment where tcpdump is running in live capture mode (without -w) which could cause it to display incorrect data, crash or enter an infinite loop.
Statement: Red Hat Product Security has rated these issues as having Moderate security impact. These issues may be fixed in a future minor release of Red Hat Enterprise Linux 7. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/sec

bugzilla·2017-02-03·CVSS 9.8
[CRITICAL] tcpdump: multiple overflow issues in protocol decoding
tcpdump: multiple overflow issues in protocol decoding
Multiple buffer overflows, and one integer overflow, in protocol decoding were found that may cause incorrect decoding, segmentation fault or (in the case of integer overflow) an infinite loop. These issues can be be exploited either locally, by making the target user decode a crafted .pcap file using tcpdump, or remotely by sending crafted packets to the network segment where the target system is running tcpdump decoding the live packet capture. Ability to send crafted packets to the target network segment is limited by the protocols' ability to cross network segments, or presence of firewall rules.
