HTTP: Microsoft Office Excel SxView SXStreamID Memory Corruption1

This signature detects attempts to exploit a known vulnerability in Microsoft Office Excel. It is due to the way Microsoft Office Excel handles specially crafted Excel files that include a malformed SxView record, allowing for memory corruption. Remote attackers can exploit this by enticing target users to open a malicious Excel file, potentially causing arbitrary code to be injected and executed in the security context of the current logged on user.
