RIM has posted a Knowledge Base article describing a critical security flaw within the BlackBerry Desktop Software. The flaw has been confirmed by Secunia, a leading vulnerability intelligence provider. Here’s the problem as described by RIM:
The BlackBerry Desktop Manager includes the Roxio Media Manager for managing media synchronization between the BlackBerry smartphone and the Microsoft Windows computer. The Roxio Media Manager includes a Microsoft ActiveX control used for retrieving and installing application updates. A buffer overflow exists in the DWUpdateService ActiveX control that could potentially be exploited when a user visits a malicious web page that invokes this control.
