Sårbar:

Referencer i sikkerhedsdatabaser:
I Debians fejlsporingssystem: Fejl 275498.
I Mitres CVE-ordbog: CVE-2004-0884.
Yderligere oplysninger:

En sårbarhed er opdaget i Cyrus' implementation af SASL-biblioteket, Simple Authentication and Security Layer, en metode til at føje autentifikationsunderstøttelse til connenction-baserede protokoller. Biblioteket respekterer miljøvariablen SASL_PATH blindt, hvilket gjorde det muligt for en lokal bruger at linke mod et ondsindet bibliotek, for at udføre vilkårlig kode med rettighederne hørende til en setuid- eller setgid-applikation.

MIT-versionen af Cyrus-implementationen af SASL-biblioteket indeholder bindinger mod MIT GSSAPI og MIT Kerberos4.

I den stabile distribution (woody) er dette problem rettet i version 1.5.24-15woody3.

I den ustabile distribution (sid) vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer dine libsasl-pakker.

Rettet i:

Debian GNU/Linux 3.0 (woody)
