2009-11-17

Berörda paket:

Sårbara:

Referenser i säkerhetsdatabaser:

I Debians felrapporteringssystem: Fel 541439.
I Mitres CVE-förteckning: CVE-2009-2409, CVE-2009-2730.

Ytterligare information:

Dan Kaminsky och Moxie Marlinspike upptäckte att gnutls, en implementation av TLS/SSL-protokollet, inte hanterar ett '\0'-tecken korrekt i ett domännamn i subjektets Common Name- eller Subject Alternative Name (SAN)-fält i ett X.509-certifikat, som tillåter mannen-i-mitten-angripare att låtsas vara godtyckliga SSL-servrar med hjälp av ett specialskrivet certifikat utgivet av en legitim certifikatsauktoritet. (CVE-2009-2730)

Dessutom, med denna uppdatering, accepteras inte längre certifikat med MD2-signaturer eftersom de inte längre anses kryptografiskt säkra. Detta påverkar bara den gamla stabila utgåvan (Etch).(CVE-2009-2409)

För den gamla stabila utgåvan (Etch) har dessa problem rättats i version 1.4.4-3+etch5 för gnutls13.

För den stabila utgåvan (Lenny) har dessa problem rättats i version 2.4.2-6+lenny2 för gnutls26.

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) har dessa problem rättats i version 2.8.3-1 för gnutls26.

Vi rekommenderar att ni uppgraderar era gnutls13/gnutls26-paket.
