tcpdump security update
Security Advisory: Low
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.
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
Please note that this update is available via Red Hat Network. To use Red
