I Mitres CVE-ordbog: CVE-2008-1948, CVE-2008-1949, CVE-2008-1950.
Yderligere oplysninger:

Flere fjernudbytbare sårbarheder er opdaget i GNUTLS, en implementering af protokolsuiten SSL/TLS.

Bemærk: Pakken libgnutls13, der leverer GNUTLS-biblioteket, indeholder ikke logik til automatisk genstart af potentielt påvirkede tjenester. Du er nødt til manuelt at genstarte påvirkede tjenester (primært Exim, vha. /etc/init.d/exim4 restart) efter opdateringen er udført, for at ændringerne kan træde hele i kraft. Alternativt kan du genstarte dit system.

Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

  • CVE-2008-1948

    Et præ-autentifikations-heapoverløb i forbindelse med for stor session resumption-data kunne føre til udførelse af vilkårlig kode.

  • CVE-2008-1949

    Gentagne klient-halloer kunne være til en præ-autentifikations-lammelsesangrebstilstand (denial of service) på grund af en null pointer-dereference.

  • CVE-2008-1950

    Dekoding af cipher-padding med en ugyldig recordlængde kunne måske få GNUTLS til at læse hukommelse ud over slutningen af den modtagne record, førende til en præ-autentifikations-lammelsesangrebstilstand.

I den stabile distribution (etch), er disse problemer rettet i version 1.4.4-3+etch1. (Opbygninger til arkitekturen arm er pt. ikke tilgængelige og vil blive frigivet senere.)

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

Vi anbefaler at du opgraderer dine GNUTLS-pakker.

Rettet i:

Debian GNU/Linux 4.0 (etch)
