Patch Available for "Stored Procedure Permissions" Vulnerability
Originally Posted:  July 7, 2000

Summary
=======
Microsoft has released a patch that eliminates a security
vulnerability in Microsoft(r) SQL Server 7.0. The vulnerability could
allow a malicious user to run a database stored procedure without
proper permissions.

Frequently asked questions regarding this vulnerability and the patch
can be found at:
http://www.microsoft.com/technet/security/bulletin/fq00-048.asp

Issue
======
Execute permission checks on stored procedures may be bypassed when a
stored procedure is referenced from a temporary stored procedure.
This omission would allow a malicious user to run a stored procedure
that, by design, he should not be able to access.

The vulnerability only occurs under a fairly restricted set of
conditions:

 - The database and stored procedure must be owned by the system
   administrator (sa) login account.

 - The malicious user must be able to authenticate to the SQL Server,
   and have user access to the referenced database.

Affected Software Versions
==========================
Microsoft SQL Server 7.0
