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 ).

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
