    This is really funny if true, I remember seeing this bug over a long period
    of time, on
    many releases of one flavor of UNIX....  wish we would fix it for once and
    for all.

    SuSE posted a UUCP bug a while back just not sure if it is the same one but
    the advisory stated that anyone using UUCP should upgrade.!

    Hello
    
    i've found buffer overflow in uucp. in BSDi platform's
    right now i've checked that on:
    
    BSDI BSD/OS 4.0.1 Kernel #1: Thu Jun 10 15:24:57 PDT 1999
    BSDI BSD/OS 3.0 Kernel #0: Thu Jan 30 13:02:43 MST 1997
    
    versions that seems to be vuln are:
    
    Version: uucp_args.c,v 2.1 1995/02/03 13:22:07 polk Exp
    "BSD/OS 4.0 98/06/11"
    
    Version: uucp_args.c,v 2.1 1995/02/03 13:22:07 polk Exp
    "BSD/OS 3.0 97/01/17"
    
    buffer overflow is based on command line argv. for ex:
    
    /usr/bin/uucp `perl -e 'print "A" x 900'` `perl -e 'print "A" x 900'`
    `perl -e 'print "A" x 356'`
    
    the ret addr is totaly writable, and it's marked as 352 - 354.
    in the thrid buffer (from left to right).
    
    since uucp is by nature suid. and the ownership is by uucp
    i don't see the real profit. what does bother me is that uucp
    also got a daemon ...
    
    Singed.
