Ytterligare information:

Flera sårbarheter har upptäckts i Clam AntiVirus, antivirussökaren för Unix som skrivits för att integreras med e-postservrar för att söka i bilagor. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

  • CVE-2005-3239

    OLE2-uppackaren gör det möjligt för angripare utifrån att orsaka ett segmenteringsfel via en DOC-fil med ett ogiltigt egenskapsträd, vilket orsakar en oändlig rekursion.

  • CVE-2005-3303

    En specialskriven exekverbar fil komprimerad med FSG 1.33 kunde få uppackaren att skriva över buffertgränserna, vilket gjorde det möjligt för angriparen att exekvera godtycklig kod.

  • CVE-2005-3500

    En specialskriven CAB-fil kunde få ClamAV att låsa sig i en oändlig slinga och använda alla tillgängliga processorresurser, vilket kan användas till en överbelastningsattack.

  • CVE-2005-3501

    En specialskriven CAB-fil kunde få ClamAV att låsa sig i en oändlig slinga och använda alla tillgängliga processorresurser, vilket kan användas till en överbelastningsattack.

Den gamla stabila utgåvan (Woody) innehåller inte clamav-paketet.

För den stabila utgåvan (Sarge) har dessa problem rättats i version 0.84-2.sarge.6.

För den instabila utgåvan (Sid) har dessa problem rättats i version 0.87.1-1.

Vi rekommenderar att ni uppgraderar era clamav-paket.
