Ytterligare information:

David Kierznowski upptäckte att libcurl, ett flerprotokollsbibliotek för filöverföring, när det är konfigurerat att följa URL-omdirigeringar automatiskt, inte ifrågasätter den nya målplatsen. Eftersom libcurl även stödjer URL:er av typen file:// och scp:// – beroende på inställningen kan en opålitlig server använda detta problem för att exponera lokala filer, skriva över lokala filer eller till och med exekvera godtycklig kod med hjälp av en illvillig URL-omdirigering.

Denna uppdatering introducerar ett nytt alternativ kallat CURLOPT_REDIR_PROTOCOLS vilket som standard inte innehåller protokollhanterarna för scp och file.

För den gamla stabila utgåvan (Etch) har detta problem rättats i version 7.15.5-1etch2.

För den stabila utgåvan (Lenny) har detta problem rättats i version 7.18.2-8lenny2.

För den instabila utgåvan (Sid) har detta problem rättats i version 7.18.2-8.1.

Vi rekommenderar att ni uppgraderar era curl-paket.
