Symantec BackupExec Calendar Buffer Overflow Exploit

This module exploits a vulnerability in the Symantec BackupExec Calendar Control (PVCalendar.ocx). When the _DOWText0 property processes a long string argument, a stack based buffer overflow occurs allowing execution of arbitrary code. This module runs a web server waiting for vulnerable clients (Internet Explorer) to connect to it. When the client connects, it will try to install an agent by exploiting this vulnerability.
