Rapporteret den:

17. jun 2010

Berørte pakker:

sudo

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 585394.
I Mitres CVE-ordbog: CVE-2010-1646.

Yderligere oplysninger:

Anders Kaseorg og Evan Broder opdagede en sårbarhed i sudo, et program der har til formål at lade en systemadministrator give begrænsede rootrettigheder til brugere, som gjorde det muligt for en bruger med sudorettigheder i visse programmer, at anvende disse med en ubetroet PATH-værdi. Det kunne muligvis føre til at visse bevidste begrænsninger blev omgået, så som indstillingen af secure_path.

I den stabile distribution (lenny), er dette problem rettet i version 1.6.9p17-3

I den ustabile distribution (sid), er dette problem rettet i version 1.7.2p7-1, og vil om kort tid blive overført til distributionen testing (squeeze).

Vi anbefaler at du opgraderer din sudo-pakke.

Rettet i:

Debian GNU/Linux 5.0 (lenny)
