SMB: MAILSLOT Heap Overflow
This signature detects attempts to exploit a known vulnerability in the SMB protocol. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the system.
Extended Description
The server driver (srv.sys) in Microsoft Windows NT 4.0, 2000, XP, and Server 2003 allows remote attackers to cause a denial of service (system crash) via an SMB_COM_TRANSACTION SMB message that contains a string without null character termination, which leads to a NULL dereference in the ExecuteTransaction function, possibly related to an "SMB PIPE," aka the "Mailslot DOS" vulnerability. NOTE: the name "Mailslot DOS" was derived from incomplete initial research; the vulnerability is not associated with a mailslot.
