I Mitres CVE-förteckning: CVE-2002-1311.

Ytterligare information:

Ett problem har upptäckts i Courier sqwebmail-paketet, ett CGI-program som ger autentiserad tillgång till lokala brevlådor. Programmet släppte inte privilegierna tillräckligt snabbt vid start under vissa förhållandet, vilket gjorde att lokala skalanvändare kunde exekvera sqwebmailbinären och därmed läsa godtyckliga filer på det lokala filsystemet.

Detta problem har rättats i version 0.37.3-2.3 för den nuvarande stabila utgåvan (Woody) samt i version 0.40.0-1 för den instabila utgåvan (Sid). Den gamla stabila utgåvan (Potato) innehåller inte några paket med Courier sqwebmail. courier-ssl påverkas inte heller då de inte exponerar sqwebmail-paketet.

Vi rekommenderar att ni uppgraderar ert sqwebmail-paket omedelbart.
