* Attackers might use this to circumvent security checks:
|
* For example, a malicious user might upload a file with the name
|
* "foo.exe\0.png". This file name might pass security checks (i.e.
|
* checks for the extension ".png"), while, depending on the underlying
|
* C library, it might create a file named "foo.exe", as the NUL
