Test case 152879

Description

This test case implements an sprintf that uses untrusted user input without a format string. The test case takes untrusted user input and passes it to an sprintf that does not implement a format string. This allows the user to pass format strings to the test case causing it to leak sensitive data and possibly allowing an attacker to cause a buffer overflow and inject shell code.
