Ethereal contains a vulnerability in the way it processes Server Message Block (SMB) packets.
The Server Message Block (SMB) protocol is used for sharing files, printers, and other resources between computers. SMB is used in Microsoft Windows to provide file and print services. Ethereal includes the ability to decode packets containing SMB data. There is a vulnerability in the way the SMB dissector decodes SMB packets containing a policy name without a handle. If SID snooping is enabled, this could trigger a null pointer dereference and a remote, unauthenticated attacker could cause Ethereal to crash or potentially execute code of the attacker's choice.
