Summary
Red Hat Security Advisory: tcpdump security, bug fix, and enhancement update
Notes
Topic
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.
Details
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, CVE-2016-7922, CVE-2016-7923, CVE-2016-7924, CVE-2016-7925, CVE-2016-7926, CVE-2016-7927, CVE-2016-7928, CVE-2016-7929, CVE-2016-7930, CVE-2016-7931, CVE-2016-7932, CVE-2016-7933, CVE-2016-7934, CVE-2016-7935, CVE-2016-7936, CVE-2016-7937, CVE-2016-7938, CVE-2016-7939, CVE-2016-7940, CVE-2016-7973, CVE-2016-7974, CVE-2016-7975, CVE-2016-7983, CVE-2016-7984, CVE-2016-7985, CVE-2016-7986, CVE-2016-7992, CVE-2016-7993, CVE-2016-8574, CVE-2016-8575, CVE-2017-5202, CVE-2017-5203, CVE-2017-5204, CVE-2017-5205, CVE-2017-5341, CVE-2017-5342, CVE-2017-5482, CVE-2017-5483, CVE-2017-5484, CVE-2017-5485, CVE-2017-5486)
