I Mitres CVE-ordbog: CVE-2009-2416, CVE-2009-2414.

Yderligere oplysninger:

Rauli Kaksonen, Tero Rontti og Jukka Taimisto opdagede flere sårbarheder i libxml2, et bibliotek til fortolkning og håndtering af XML-datafiler, hvilket kunne føre til lammelsesangreb (denial of service) eller muligvis udførelse af vilkårlig kode i den applikation, som anvender biblioteket. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

CVE-2009-2416
Et XML-dokument med særligt fremstillede Notation- eller Enumeration-attributtyper i en DTD-definition, førte til anvendelse af pointere til hukommelsesarealer, der allerede var frigivet.
CVE-2009-2414
Manglende kontrol af dybden af ELEMENT DTD-definitioner, ved fortolkning af child-indhold, kunne føre til omfattende stakvækst på grund af en funktionsrekursion, hvilket kunne udløses af et fabrikeret XML-dokument.

I den gamle stabile distribution (etch), er dette problem rettet i version 2.6.27.dfsg-6+etch1.

I den stabile distribution (lenny), er dette problem rettet i version 2.6.32.dfsg-5+lenny1.

I distributionen testing (squeeze) og i den ustabile (sid) distribution, vil dette problem snart blive rettet.

Vi anbefaler at du opgraderer dine libxml2-pakker.
