Berørte pakker:

libxml2

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2010-4008.

Yderligere oplysninger:

Bui Quang Minh opdagede at libxml2, et bibliotek til fortolkning og håndtering af XML-datafiler, ikke behandlede en misdannet XPATH særlig godt, dette forårsagede et nedbrud og muliggjorde udførelse af vilkårlig kode.

I den stabile distribution (lenny), er dette problem rettet i version 2.6.32.dfsg-5+lenny2.

I distributionen testing (squeeze) og i den ustabile distribution (sid), er dette problem rettet i version 2.7.8.dfsg-1.

Vi anbefaler at du opgraderer din libxml2-pakke.

Rettet i:

Debian GNU/Linux 5.0 (lenny)
