Flere sårbarheder er opdaget i GNOME's XML-bibliotek. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

  • CVE-2008-4225

    Drew Yao opdagede at manglende fornuftighedskontrol af inddata i funktionen xmlBufferResize() måske kunne føre til en uendelig løkke, medførende lammelsesangreb (denial of service).

  • CVE-2008-4226

    Drew Yao opdagede at et heltalsoverløb i funktionen xmlSAX2Characters() måske kunne føre til lammelsesangreb eller udførelse af vilkårlig kode.

I den stabile distribution (etch), er disse problemer rettet i version 2.6.27.dfsg-6.

I denkommende stabile distribution (lenny) og i den ustabile distribution (sid), er disse problemer rettet i version 2.6.32.dfsg-5.

Vi anbefaler at du opgraderer dine libxml2-pakker.
