SAP BusinessObjects BI Platform 4.1, BusinessObjects Edge 4.0, and BusinessObjects XI (BOXI) 3.1 R3 allow remote attackers to cause a denial of service (out-of-bounds read and listener crash) via a crafted GIOP packet, aka SAP Security Note 2001108.

SAP BusinessObjects 4.0 and BusinessObjects XI (BOXI) R2 and 3.1 generates error messages for a failed logon attempt with different time delays depending on whether the user account exists, which allows remote attackers to enumerate valid usernames via SecEnterprise authentication requests to the Session web service.
