CentOS Errata and Security Advisory CESA-2017:1871

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)
