TPTI-08-06: Landesk QIP Server Service Heal Packet Buffer Overflow Vulnerability http://dvlabs.tippingpoint.com/advisory/TPTI-08-06 September 15, 2008 -- CVE ID: CVE-2008-2468 -- Affected Vendors: LANDesk -- Affected Products: LANDesk Management Suite -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 6411. For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of LANDesk Management Suite. Authentication is not required to exploit this vulnerability. The specific flaw exists within the QIP Server Service (qipsrvr.exe) which listens by default on TCP port 12175. The process makes a vulnerable call to MultiByteToWideChar using values obtained from packet data. A malicious \'heal\' request can allow an attacker to control both the pointer to the StringToMap and the StringSize arguments. The destination buffer is either allocated on the stack or heap depending on the specified sizes. In both cases it can be overflown leading to arbitrary code execution under the context of the SYSTEM user. -- Vendor Response: LANDesk has issued an update to correct this vulnerability.
