This module exploits a stack based buffer overflow in VideoCharge Studio 2.12.3.685 when
processing a specially crafted .VSC file. This vulnerability could be
exploited by a remote attacker to execute arbitrary code on the target
machine by enticing a user of VideoCharge Studio to open a malicious .VSC file.
