    CVE Ids        : CAN-2004-0408
    
    Jack <This email address is being protected from spambots. You need JavaScript enabled to view it.> discovered a buffer overflow in
    ident2, an implementation of the ident protocol (RFC1413), where a
    buffer in the child_service function was slightly too small to hold
    all of the data which could be written into it.  This vulnerability
    could be exploited by a remote attacker to execute arbitrary code with
    the privileges of the ident2 daemon (by default, the "identd" user).
    
    For the current stable distribution (woody) this problem has been
    fixed in version 1.03-3woody1.
    
    For the unstable distribution (sid), this problem will be fixed soon.
    
    We recommend that you update your ident2 package.
