1. Summary:
An update for tcpdump is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64
Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64
Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 7) - x86_64
3. Description:
The tcpdump packages contain the tcpdump utility for monitoring network
traffic. The tcpdump utility can capture and display the packet headers on
a particular network interface or on all interfaces.
The following packages have been upgraded to a later upstream version:
tcpdump (4.9.0). (BZ#1422473)
Security Fix(es):
* 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. (CVE-2015-0261, CVE-2015-2153, CVE-2015-2154, CVE-2015-2155,
