RHSA-2003-305: zebra

Vulnerability Assessment Summary
Check for the version of the zebra packages

Detailed Explanation for this Vulnerability Assessment


Updated zebra packages that close a locally-exploitable and a
remotely-exploitable denial of service vulnerability are now available.

Zebra an open source implementation of TCP/IP routing software.

Jonny Robertson reported that Zebra can be remotely crashed if a Zebra
password has been enabled and a remote attacker can connect to the Zebra
telnet management port. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2003-0795 to this issue.

Herbert Xu reported that Zebra can accept spoofed messages sent on the
kernel netlink interface by other users on the local machine. This could
lead to a local denial of service attack. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2003-0858 to
this issue.

Users of Zebra should upgrade to these erratum packages, which contain
a patch preventing Zebra from crashing when it receives a telnet option
delimiter without any option data, and a patch that checks that netlink
messages actually came from the kernel.
