Yderligere oplysninger:

To sikkerhedsproblemer er opdaget i Ghostscript, GPL-fortolkeren af PostScript/PDF. Projektet Common Vulnerabilities and Exposures har registreret følgende problemer:

CVE-2009-4897
Et bufferoverløb blev opdaget, som gjorde det muligt for fjernangribere at udføre vilkårlig kode eller forårsage lammelsesangreb (denial of service) gennem et fabrikeret PDF-dokument indeholdende et langt navn.
CVE-2010-1628
Dan Rosenberg opdagede at ghostscript på ukorrekt vis håndterede visse rekursive PostScript-filer. En angriber kunne udføre vilkårlig kode gennem en PostScript-fil indeholdende ubegrænsede rekursive procedurekald, hvilket udløste hukommelseskorruption i fortolkerens stak.

I den stabile distribution (lenny), er disse problemer rettet i version 8.62.dfsg.1-3.2lenny5

I distributionen testing (squeeze) og i den ustabile distribution (sid), er disse problemer rettet i version 8.71~dfsg2-4

Vi anbefaler at du opgraderer din ghostscript-pakke.
