(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.

    http://arthur.ath.cx/pipermail/ngircd-ml/2005-January/000228.html


Solution: 
    All ngIRCd users should upgrade to the latest version:
    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-irc/ngIRCd-0.8.2"
  

Risk factor : High
