    Package        : ircd-hybrid/ircd-ratbox
    Vulnerability  : integer underflow/denial of service
    Problem type   : remote
    Debian-specific: no
    CVE Ids        : CVE-2009-4016 CVE-2010-0300
    
    
    David Leadbeater discovered an integer underflow that could be triggered
    via the LINKS command and can lead to a denial of service or the
    execution of arbitrary code (CVE-2009-4016). This issue affects both,
    ircd-hybrid and ircd-ratbox.
    
    It was discovered that the ratbox IRC server is prone to a denial of
    service attack via the HELP command. The ircd-hybrid package is not
    vulnerable to this issue (CVE-2010-0300).
    
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1:7.2.2.dfsg.2-4+lenny1 of the ircd-hybrid package and in
    version 2.2.8.dfsg-2+lenny1 of ircd-ratbox.
    
    Due to a bug in the archive software it was not possible to release the
    fix for the oldstable distribution (etch) simultaneously. The packages
    will be released as version 7.2.2.dfsg.2-3+etch1 once they become
    available.
    
    For the testing distribution (squeeze) and the unstable distribution
    (sid), this problem will be fixed soon.
    
    
    We recommend that you upgrade your ircd-hybrid/ircd-ratbox packages.
