DB: MS-SQL Pre-Auth Overflow
This protocol anomaly detects a buffer overflow in the SQL server pre-auth message. This can indicate your system is being attacked and if successful, might cause a denial of service or allow the attacker to execute arbitrary code.
Extended Description
A vulnerability has been discovered in Microsoft SQL Server that could make it possible for remote attackers to gain access to target hosts. It is possible for an attacker to cause a buffer overflow condition on the vulnerable SQL server with a malformed login request. This may allow a remote attacker to execute arbitrary code as the SQL Server process. This vulnerability reportedly occurs even before authentication can proceed.
