(ngIRCd: Buffer overflow)

    Florian Westphal discovered a buffer overflow caused by an integer
    underflow in the Lists_MakeMask() function of lists.c.
  
Impact :

    A remote attacker can exploit this buffer overflow to crash the ngIRCd
    daemon and possibly execute arbitrary code with the rights of the
    ngIRCd daemon process.
  
Workaround :

    There is no known workaround at this time."
