Microsoft Server Message Block (SMB) may crash upon receipt of a crafted SMB_COM_TRANSACTION packet requesting a NetServerEnum3 transaction. Attackers can use this vulnerability to cause a denial of service.
SMB is a protocol for sharing data and resources between computers, included in many versions of Microsoft Windows.
SMB may crash if it receives a crafted SMB_COM_TRANSACTION packet requesting a NetServerEnum2 transaction. If either the 'Max Param Count' field or 'Max Data Count' field of the packet is set to zero (0), the destination SMB host will crash with a blue screen. This vulnerability can be exploited by both local and remote attackers.
Remote attackers can cause a denial of service. Attackers may also be able to execute arbitrary code, though this has not been demonstrated or proven.
