Follow-up on Lumigent Log Explorer 3.xx extended stored procedures buffer overflow

Thanks to Martin for pointing this out. We did reply to him but apparently
not before his posting. This issue will be fixed in our next scheduled
maintenance release, available in two to three weeks.

In the meantime, we recommend that you grant execute permissions on
Lumigent's extended stored procedures to trusted logins only (a useful
policy in any case).
This prevents untrusted users from invoking stored procedures with
malicious intent.

Thanks,
--Murray

overflow

Lumigent Log Explorer is a transaction log explorer for Microsoft SQL
Server 7/2000. It ships with extended stored procedures implemented in
xp_logattach.dll. Some of them suffer from buffer overflows that lead to
SQL Server service crash and potentially to arbitrary code execution.
Below is sample code that crashes SQL Server:

...
Procedures can be run only by dbo (master) by default. Vendor was informed
but I got no response confirming this problem and no fixes.
