Description

Updated tcpdump, libpcap, and arpwatch packages fix vulnerabilities in ISAKMP parsing.

Tcpdump is a command-line tool for monitoring network traffic. Tcpdump v3.8.1 and earlier versions contained multiple flaws in the packet display functions for the ISAKMP protocol. Upon receiving specially crafted ISAKMP packets, TCPDUMP would try to read beyond the end of the packet capture buffer and subsequently crash. Users of tcpdump are advised to upgrade to these erratum packages, which contain backported security patches and are not vulnerable to these issues.

Solution(s)

  • redhat-upgrade-arpwatch
  • redhat-upgrade-libpcap
  • redhat-upgrade-tcpdump
