Subject: SAP database local root via symlink

Hey folks,
    During an evaluation of the SAP database for linux I located a 
security issue in one of their suid binaries. This issue is a symlink 
attack against a binary that makes an execve call to a file in your 
current directory. The details of this issue are outlined below. You 
should be able to exploit this by hand however I included a simple exploit.

The alert from SAP is located here:
http://www.sapdb.org/sap_db_alert.htm

This code and alert will be added to http://www.snosoft.com/research
