Rapporterat den:

2008-01-13

Berörda paket:

libxml2

Sårbara:

Referenser i säkerhetsdatabaser:

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

Ytterligare information:

Brad Fitzpatrick upptäckte att UTF-8-avkodningsfunktionerna i libxml2, GNOMEs XML-bibliotek, inte utförde tillräckliga kontroller av UTF-8-korrekthet, vilket kunde användas i en överbelastningsattack genom att tvinga in libxml2 i en oändlig slinga.

För den gamla stabila utgåvan (Sarge) har detta problem rättats i version 2.6.16-7sarge1.

För den stabila utgåvan (Etch) har detta problem rättats i version 2.6.27.dfsg-2.

För den instabila utgåvan (Sid) kommer detta problem rättas inom kort.

Vi rekommenderar att ni uppgraderar era libxml2-paket.
