Rapporteret den:

17. nov 2009

Berørte pakker:

gnutls13, gnutls26

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 541439.
I Mitres CVE-ordbog: CVE-2009-2409, CVE-2009-2730.

Yderligere oplysninger:

Dan Kaminsky og Moxie Marlinspike opdagede at gnutls, en implementering af TLS-/SSL-protokollen, ikke på korrekt vis håndterede \0-tegn i et domænenavn i emnets Common Name- eller Subject Alternative Name-felt (SAN) i et X.509-certifikat, hvilket tillod manden i midten-angreb i forbindelse med forfalskning af vilkårlig SSL-servere gennem et fabrikeret certifikat udstedt af en legitim Certification Authority. (CVE-2009-2730)

Desuden accepteres der fra og med denne opdatering ikke certifikater med MD2 hash-signaturer, da de ikke længere anses for at være kryptografisk sikre. Det påvirker kun den gamle stabile distribution (etch). (CVE-2009-2409)

I den gamle stabile distribution (etch), er disse problemer rettet i version 1.4.4-3+etch5 af gnutls13.

I den stabile distribution (lenny), er disse problemer rettet i version 2.4.2-6+lenny2 af gnutls26.

I distributionen testing (squeeze) og i den ustabile distribution (sid), er disse problemer rettet i version 2.8.3-1 af gnutls26.

Vi anbefaler at du opgraderer dine gnutls13/gnutls26-pakker.
