Signature Detail

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

Microsoft Windows Server driver is prone to a remote heap buffer-overflow vulnerability. This issue is due to a failure of the software to properly bounds check user-supplied input prior to copying it to an insufficiently-sized memory buffer. Exploiting this issue allows anonymous, remote attackers to execute arbitrary machine code in the context of the affected driver. This facilitates the complete compromise of affected computers. Microsoft Windows XP SP2 and Microsoft Windows Server 2003 SP1 are not vulnerable to this issue in their default configuration.
