Weitere Informationen:

Mehrere Verwundbarkeiten wurden in Clam AntiVirus entdeckt, dem Antivirenscanner für Unix, der für die Integration in Mailserver ausgelegt ist, um Dateianhänge zu durchsuchen. Das Common Vulnerabilities and Exposures project identifiziert die folgenden Probleme:

  • CVE-2005-3239

    Der OLE2-Entpacker ermöglicht entfernten Angreifern, einen segmentation fault mittels einer DOC-Datei mit fehlerhaftem Eigenschaftenbaum zu verursachen. Dadurch wird eine endlose Rekursion ausgelöst.

  • CVE-2005-3303

    Eine speziell präparierte ausführbare Datei, die mit FSG 1.33 komprimiert wurde, kann den Entpacker dazu bringen, über Puffergrenzen hinaus zu schreiben. Dadurch kann ein Angreifer beliebigen Code ausführen.

  • CVE-2005-3500

    Eine speziell präparierte CAB-Datei kann ClamAV in eine Endlosschleife bringen, die alle verfügbaren Prozessorressourcen aufbraucht. Dadurch wird ein Denial of Service ausgelöst.

  • CVE-2005-3501

    Eine speziell präparierte CAB-Datei kann ClamAV in eine Endlosschleife bringen, die alle verfügbaren Prozessorressourcen aufbraucht. Dadurch wird ein Denial of Service ausgelöst.

Die alte Stable-Distribution (Woody) enthält das clamav-Paket nicht.

Für die Stable-Distribution (Sarge) wurden diese Probleme in Version 0.84-2.sarge.6 behoben.

Für die Unstable-Distribution (Sid) wurden diese Probleme in Version 0.87.1-1 behoben.

Wir empfehlen Ihnen, Ihre clamav-Pakete zu aktualisieren.

Debian GNU/Linux 3.1 (sarge)
