Sårbara:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 8518.
I Mitres CVE-förteckning: CVE-2003-0743.

Ytterligare information:

Det finns ett buffertspill i exim, som är den förvalda e-postservern i Debian. Genom att sända specialskrivna HELO- eller EHLO-kommandon kunde en angripare få en konstant sträng att skrivas bortom slutet på en buffert som allokerats på heap:en. Denna sårbarhet tros för närvarande inte kunna utnyttjas för att exekvera godtycklig kod.

För den stabila utgåvan (Woody) har detta problem rättats i exim version 3.35-1woody2 och exim-tls version 3.35-3woody1.

För den instabila utgåvan (Sid) har detta problem rättats i exim version 3.36-8. Den instabila utgåvan innehåller inte något exim-tls-paket.

Vi rekommenderar att ni uppgraderar ert exim- eller exim-tls-paket.
