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

Ytterligare information:

Rauli Kaksonen, Tero Rontti och Jukka Taimisto upptäckte flera sårbarheter i libxml, ett bibliotek för tolkning och hantering av XML-datafiler, vilka kan leda till överbelastning eller möjligen godtycklig kodexekvering i den applikation som använder biblioteket. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

CVE-2009-2416
Ett XML-dokument med specialskrivna Notation- eller Enumeration-attributtyper i en DTD-definition leder till användandet av pekare till minnesområden som redan har frisläppts.
CVE-2009-2414
Saknade kontroller för djupet av ELEMENT-DTD-definitioner vid tolkning av barninnehåll kan leda till kraftig ökning av data på stacken på grund av funktionsrekursion som kan startas med hjälp av ett specialskrivet XML-dokument.

För den gamla stabila utgåvan (Etch) har detta problem rättats i version 1.8.17-14+etch1.

Den stabila (Lenny), uttestnings- (Squeeze) och den instabila (Sid) utgåvan inehåller inte libxml, men innehåller istället libxml2 för vilken DSA-1859-1 har släppts.

Vi rekommenderar att ni uppgraderar era libxml-paket.
