Yderligere oplysninger:

Der er rapporteret to sårbarheder i sendmail.

CAN-2003-0681:
Et "potentielt bufferoverløb i tolkningen af regelsæt" i Sendmail 8.12.9, når et ikke-standardregelsæt anvendes (1), modtager (2) eller slutteligt (3) mailer-specifikke envelope-modtagere, har ukendte konsekvenser.
CAN-2003-0694:
Funktionen prescan i Sendmail 8.12.9 gør det muligt for fjernangribere at udføre vilkårlig kode via bufferoverløb-angreb, som demonstreret ved hjælp af funktionen parseaddr i parseaddr.c.

I den stabile distribution (woody) er disse problemer rettet i sendmail version 8.12.3-6.6 og sendmail-wide version 8.12.3+3.5Wbeta-5.5.

I den ustabile distribution (sid) er disse problemer rettet i sendmail version 8.12.10-1.

Vi anbefaler at du opdaterer din sendmail-pakke.
