Weitere Informationen:

Der ursprüngliche Entwickler von curl, einer multiprotokollfähigen Bibliothek zur Dateiübertragung, hat uns darüber informiert, dass die frühere Korrektur von diversen Off-by-one-Fehlern nicht ausreichend war. Der Vollständigkeit halber ist unten der Text der ursprünglichen Fehlerbeschreibung wiedergegeben:

Mehrere Probleme wurden in libcurl entdeckt, einer multiprotokollfähigen Bibliothek zur Dateiübertragung. Das Common Vulnerabilities and Exposures project identifiziert die folgenden Probleme:

CVE-2005-3185
Ein Pufferüberlauf wurde in libcurl entdeckt, der die Ausführung von beliebigem Code zur Folge haben kann.

CVE-2005-4077
Stefan Esser entdeckte mehrere Off-by-one-Fehler, die lokalen Benutzern ermöglichen, einen Pufferüberlauf auszulösen und einen Denial of Service zu verursachen, oder aber Sicherheitsbeschränkungen von PHP über bestimmte URLs zu umgehen.

Für die alte Stable-Distribution (Woody) wurden diese Probleme in Version 7.9.5-1woody2 behoben.

Für die Stable-Distribution (Sarge) wurden diese Probleme in Version 7.13.2-2sarge5 behoben. Diese Aktualisierung enthält außerdem eine Fehlerkorrektur gegen Datenzerstörung.

Für die Unstable-Distribution (Sid) wurden diese Probleme in Version 7.15.1-1 behoben.

Wir empfehlen Ihnen, Ihre libcurl-Pakete zu aktualisieren.
