Unchecked Buffer in MSN Chat Control Can Lead to Code | |
|
||
| Time: 00:00 EST/05:00 GMT | News Source: Microsoft TechNet Security | Posted By: Todd Richardson | ||
|
The MSN Chat control is an ActiveX control that allows groups of users to gather in a single, virtual location online to engage in text messaging. The control is offered for download as a single ActiveX control from a number of MSN sites. In addition, it is included with MSN Messenger since version 4.5 and Exchange Instant Messenger. While the MSN Chat control is included with these products it is not used to provide Instant Messaging functionality, but rather to add chat functionality to those products. An unchecked buffer exists in one of the functions that handles input parameters in the MSN Chat control. A security vulnerability results because it is possible for a malicious user to levy a buffer overrun attack and attempt to exploit this flaw. A successful attack could allow code to run in the user's context. | ||
