Sårbar:

Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 498768.
I Mitres CVE-ordbog: CVE-2008-3529.

Yderligere oplysninger:

Man har opdaget at libxml2, GNOME's XML-bibliotek, ikke på korrekt vis håndterede lange entitetsnavne. Derved kunne det være muligt at udføre vilkårlig kode gennem en ondsindet XML-fil.

I den stabile distribution (etch), er dette problem rettet i version 2.6.27.dfsg-5.

I den ustabile distribution (sid), er dette problem rettet i version 2.6.32.dfsg-4.

Vi anbefaler at du opgraderer din libxml2-pakke.

Rettet i:

Debian GNU/Linux 4.0 (etch)
