    Package        : zebra
    Vulnerability  : denial of service
    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CAN-2003-0795 CAN-2003-0858
    
    Two vulnerabilities were discovered in zebra, an IP routing daemon:
    
    CAN-2003-0795 - a bug in the telnet CLI could allow a remote attacker
    to cause a zebra process to crash, resulting in a denial of service.
    
    CAN-2003-0858 - netlink messages sent by other users (rather than the
    kernel) would be accepted, leading to a denial of service.
    
    For the current stable distribution (woody) this problem has been
    fixed in version 0.92a-5woody2.
    
    The zebra package has been obsoleted in the unstable distribution by
    GNU Quagga, where this problem was fixed in version 0.96.4x-4.
    
    We recommend that you update your zebra package.
