The following is a Security Bulletin from the Microsoft Product Security Notification Service. Please do not reply to this message, as it was sent from an unattended mailbox. ******************************** -----BEGIN PGP SIGNED MESSAGE----- - ---------------------------------------------------------------------- Title: Visual Studio VB-TSQL Object Contains Unchecked Buffer Date: 27 March 2001 Software: Visual Studio 6.0 Enterprise Edition Impact: Run code of attacker's choice Bulletin: MS01-018 Microsoft encourages customers to review the Security Bulletin at: http://www.microsoft.com/technet/security/bulletin/MS01-018.asp. - ---------------------------------------------------------------------- Issue: ====== The VB-TSQL debugger object that ships with Visual Studio 6.0 Enterprise Edition has an unchecked buffer in the code that processes parameters for one of the object's methods. Theobject can, by design, be programmatically accessed remotely. If the object were to be referenced by a program that contained specially malformed data within the parameter, eitherof two outcomes would result. In the less serious case, the attacker could cause the object to fail on the hosting machine. In the more serious case, the attacker could exploit the buffer overrun to run code of the attacker's choice on the hosting machine. The debugger object (vbsdicli.exe) is installed by default with Visual Studio 6.0 Enterprise Edition and runs in the context of the interactively logged-on user. The attacker could only execute a successful attack if he knew that a user had the component installed and that the user was logged in at the time of the attack. Mitigating Factors: =================== - If best practices have been followed and ports 137-139 and 445 have been blocked at an organization's router or firewall, this attack could not be executed from the Internet. - There is no way to determine remotely if a machine has the affected component installed. An attacker would need to successively target machines until he found one that was susceptible. - The vulnerability could only be exploited if an interactive user were logged on to the target machine at the time of the malicious user's attack. - Only the Enterprise Edition of Visual Studio 6.0 is affected. Visual Studio 6.0 Professional Edition is not affected. Patch Availability: =================== - A patch is available to fix this vulnerability. Please read the Security Bulletin http://www.microsoft.com/technet/security/bulletin/ms01-018.asp for information on obtaining this patch.
