DSA-1461-1 libxml2 -- manglende kontrol af inddata

Rapporteret den:

13. jan 2008

Berørte pakker:

libxml2

Sårbar:

Referencer i sikkerhedsdatabaser:

I Mitres CVE-ordbog: CVE-2007-6284.

Yderligere oplysninger:

Brad Fitzpatrick opdagede at UTF-8-dekodningsfunktionerne i libxml2, GNOMEs XML-bibliotek, validerede UTF-8-korrekthed på utilstrækkelig vis, hvilket kunne føre til lammelsesangreb (denial of service) ved at tvinge libxml2 ind i en uendelig løkke.

I den gamle stabile distribution (sarge), er dette problem rettet i version 2.6.16-7sarge1.

I den stabile distribution (etch), er dette problem rettet i version 2.6.27.dfsg-2.

I den ustabile distribution (sid), vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer dine libxml2-pakker.
