Ytterligare information:

Man har upptäckt flera sårbarheter i tolken för språket Python. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

CVE-2007-2052
Piotr Engelking upptäckte att funktionen strxfrm() i locale-modulen räknar fel på längden på en intern buffert, vilket kunde leda till en mindre informationsläcka.
CVE-2007-4965
Man har upptäckt att flera heltalsspill i imageop-modulen kunde leda till exekvering av godtycklig kod om en användare luras till att behandla felaktiga bilder. Detta problem spåras även som CVE-2008-1679 på grund av en ofullständig inledande patch.
CVE-2008-1721
Justin Ferguson upptäckte att ett buffertspill i zlib-modulen kunde leda till exekvering av godtycklig kod.
CVE-2008-1887
Justin Ferguson upptäckte att otillräcklig städning av indata i funktionen PyString_FromStringAndSize() kunde leda till exekvering av godtycklig kod.

För den stabila utgåvan (Etch) har dessa problem rättats i version 2.5-5+etch1.

För den instabila utgåvan (Sid) har dessa problem rättats i version 2.5.2-3.

Vi rekommenderar att ni uppgraderar era python2.5-paket.
