An arbitrary code execution can be achieved if loading code from untrusted
current working directory despite the '.' is removed from @INC. Vulnerability
is in XSLoader that uses caller() information to locate .so file to load. If
malicious attacker creates directory named `(eval 1)` with malicious binary
file in it, it will be loaded if the package calling XSLoader is in parent
directory.
