Berørte pakker:

ircd-hybrid/ircd-ratbox

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2009-4016, CVE-2010-0300.

Yderligere oplysninger:

David Leadbeater opdagede et heltalsunderløb, der kunne udløses gennem kommandoen LINKS, og kunne føre til et lammelsesangreb (denial of service) eller udførelse af vilkårlig kode (CVE-2009-4016). Problemet påvirker både ircd-hybrid og ircd-ratbox.

Man opdagede at IRC-serveren ratbox var sårbar over for et lammelsesangreb gennem kommandoen HELP. Pakken ircd-hybrid er ikke ramt af dette problem (CVE-2010-0300).

I den stabile distribution (lenny), er dette problem rettet i version 1:7.2.2.dfsg.2-4+lenny1 af pakken ircd-hybrid og i version 2.2.8.dfsg-2+lenny1 af ircd-ratbox.

På grund af en fejl i arkiveringsprogrammellet, var det ikke muligt på samme tid at udgive en rettelse til den gamle stabile distribution (etch). Pakken vil blive udgivet som version 7.2.2.dfsg.2-3+etch1, når den er klar.

I distributionen testing (squeeze) og i den ustabile distribution (sid), vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer dine ircd-hybrid/ircd-ratbox-pakker.
