| Business Impact: |
Microsoft DirectShow is a software interface used by most Windows-based applications, such as Microsoft Media Player, that manage multimedia files. Although this vulnerability may require some user interaction, a successful exploit would result in remote code execution and possibly complete compromise of the system. The widespread nature of Microsoft DirectShow coupled with the impact of the vulnerability means this issue should be considered highly critical. |
