| Business Impact: |
Microsoft DirectShow is a core component of Microsoft Windows 2000, XP, and Server 2003 and is enabled by default. Successful exploitation of this issue would provide an attacker with complete control over the endpoint target. The use of malicious media files like images and movies has been prevalent in the past years and the use of malicious movies, in particular, substantially increased near the end of 2008. Although no public exploits are currently available, customers that are using the affected operating systems should consider immediate deployment of patches and protection for this issue. |
