    GENTOO LINUX SECURITY ANNOUNCEMENT 200301-2
    - - --------------------------------------------------------------------

    PACKAGE : leafnode
    SUMMARY : denial of service
    DATE    : 2003-01-02 11:01 UTC
    EXPLOIT : local and remote

    - - --------------------------------------------------------------------

    - From leafnode advisory:

    "This vulnerability can make leafnode's nntpd server, named leafnode, go
    into an unterminated loop when a particular article is requested. The
    connection becomes irresponsive, and the server hogs the CPU. The client
    will have to terminate the connection and connect again, and may fall
    prey to the same problem; ultimately, there may be so many leafnode
    processes hogging the CPU that no serious work is possible any more and
    the super user has to kill all running leafnode processes."

    http://marc.theaimsgroup.com/?l=bugtraq&m=104127108823436&w=2

    SOLUTION

    It is recommended that all Gentoo Linux users who are running
    new-news/leafnode-1.9.24 or earlier update their systems as
    follows:

    emerge rsync
    emerge leafnode
    emerge clean
