postfix
Sårbar:

Referencer i sikkerhedsdatabaser:
I Mitres CVE-ordbog: CVE-2003-0468, CVE-2003-0540.
Yderligere oplysninger:

Posttransport-programmet postfix i Debian 3.0 indeholder to sårbarheder:

  • CAN-2003-0468: Postfix tillod en angriber at foretage "bounce-scan" af private netværk eller anvende dæmonen som et DDoS-værktøj, ved at tvinge den til at tilslutte sig en vilkårlig tjenste på en vilkårlig IP-adresse og enten modtage en bounce-meddelelse eller holde øje med kø-handlinger for at gætte sig til status på leveringsforsøget.
  • CAN-2003-0540: En misdannet envelope-adresse kan 1) få kø-håndteringsprogrammet til at låse indtil en post fjernes fra køen og 2) få SMTP-lytteprogrammet til at låse, resulterende i et lammelsesangreb.

I den nuværende stabile distribution (woody) er disse problemer rettet i version 1.1.11-0.woody3.

I den ustabile distribution (sid) vil disse problemer snart blive rettet.

Vi anbefaler at du opdaterer din postfix-pakke.

Rettet i:

Debian GNU/Linux 3.0 (woody)
