DSA-975-1 nfs-user-server -- bufferoverløb

Rapporteret den:

15. feb 2006

Berørte pakker:

nfs-user-server

Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 350020.
I Mitres CVE-ordbog: CVE-2006-0043.

Yderligere oplysninger:

Marcus Meissner har opdaget at angribere kunne udløse et bufferoverløb i stihåndteringskoden ved at oprette eller misbruge eksisterende symlinks, hvilket kunne føre til udførelse af vilkårlig kode.

Denne sårbarhed findes ikke i kernens NFS-server.

Opdateringen indeholder en fejlrettelse til attributhåndteringen af symlinks. Rettelsen har ikke sikkerhedsimplikationer, men da denne DSA blev forberedt var rettelsen allerede i kø til at blive optaget i den næste punktopdatering af den stabile udgave, hvorfor vi besluttede at medtage den med det samme.

I den gamle stabile distribution (woody) er dette problem rettet i version 2.2beta47-12woody1.

I den stabile distribution (sarge) er dette problem rettet i version 2.2beta47-20sarge2.

I den ustabile distribution (sid) er dette problem rettet i version 2.2beta47-22.

Vi anbefaler at du opgraderer din nfs-user-server-pakke.
