I Mitres CVE-ordbog: CVE-2008-2469.

Yderligere oplysninger:

Dan Kaminsky opdagede at libspf2, en implementering af Sender Policy Framework (SPF), der anvendes af mailservere til filtrering af mail, håndterede misdannede TXT-poster på ukorrekt vis, førende til en bufferoverløbstilstand (CVE-2008-2469).

Bemærk at SPF-konfigurationsskabelonen i Debians Exim-opsætning, anbefaler at anvende libmail-spf-query-perl, der ikke er ramt af dette problem.

I den stabile distribution (etch), er dette problem rettet i version 1.2.5-4+etch1.

I distributionen testing (lenny), er dette problem rettet i version 1.2.5.dfsg-5+lenny1.

I den ustabile distribution (sid), vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer din libspf2-pakke.

Rettet i:

Debian GNU/Linux 4.0 (etch)
