A buffer overflow in Microsoft Collaboration Data Objects may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Microsoft Collaboration Data Objects (CDO) is a scripting library used to develop applications that handle email. Note that CDO is commonly associated with cdosys.dll and codex.dll. An input validation error in CDO may allow a buffer overflow to occur in applications or components that use CDO. If a remote, unauthenticated attacker supplies an application or component that uses CDO with a specially crafted message, that attacker may be able to trigger the buffer overflow and, consequently, execute arbitrary code.
For more information, including a list of affected software, please see MS05-048. Please note that exploit code for this vulnerability is publicly available.
If a remote attacker supplies an application that uses CDO with a specially crafted message, that attacker may be able execute arbitrary code on a vulnerable system.
