RHSA-2003-305: zebra |

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.
