Potential file system race condition (CWE-367) in getConfigurationFileOptions()

[sjinks]

Often it is necessary to check the state of a file before using it. These checks usually take a file name to be checked, and if the check returns positively, then the file is opened or otherwise operated upon.

However, in the time between the check and the operation, the underlying file referenced by the file name could be changed by an attacker, causing unexpected behavior.
