Curls uppströmsförfattare, ett bibliotek för filöverföring för flera protokoll, informerade oss att den tidigare rättningen till flera stegfel inte är tillräcklig. Texten från originalbulletinen följer nedan:

Flera problem har upptäckts i libcurl, ett bibliotek för filöverföring för flera protokoll. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

CVE-2005-3185
Ett buffertspill har upptäckts i libcurl, vilket kunde göra det möjligt att exekvera godtycklig kod.

CVE-2005-4077
Stefan Esser upptäckte flera stegfel (off-by-one) vilka gjorde det möjligt för lokala användare att utlösa ett buffertspill och utföra en överbelastningsattack eller gå förbi PHP-säkerhetsrestriktioner via specifika URL:er.

För den gamla stabila utgåvan (Woody) har dessa problem rättats i version 7.9.5-1woody2.

För den stabila utgåvan (Sarge) har dessa problem rättats i version 7.13.2-2sarge5. Denna uppdatering innehåller även en korrigering fel i data.

För den instabila utgåvan (Sid) har dessa problem rättats i version 7.15.1-1.

Vi rekommenderar att ni uppgraderar era libcurl-paket.
