DSA-1473-1 scponly -- designfejl

Rapporteret den:

21. jan 2008

Berørte pakker:

scponly

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 437148.
I Mitres CVE-ordbog: CVE-2007-6350, CVE-2007-6415.

Yderligere oplysninger:

Joachim Breitner opdagede at Subversion-understøttelsen i scponly generelt er usikker, hvilket gjorde det muligt for udføre vilkårlige kommandoer. Yderligere undersøgelser viste at rsync- og Unison-understøttelsen var ramt af lignende problemer. Disse problemer har fået tildelt CVE-2007-6350.

Desuden opdagede man at det var muligt, at kalde scp med visse valgmuligheder, der kunne føre til udførelse af vilkårlige kommandoer (CVE-2007-6415).

Denne opdatering fjerner understøttelse af Subversion, rsync og Unison fra pakken scponly, og forhindrer scp i at blive kaldt med farlige valgmuligheder.

I den gamle stabile distribution (sarge), er disse problemer rettet i version 4.0-1sarge2.

I den stabile distribution (etch), er disse problemer rettet i version 4.6-1etch1.

Den ustabile distribution (sid) vil snart blive rettet.

Vi anbefaler at du opgraderer din scponly-pakke.
