Security (GNU tar 1.35)

### 10.2 Security

In some cases `tar` may be used in an adversarial situation, where an untrusted user is attempting to gain information about or modify otherwise-inaccessible files. Dealing with untrusted data (that is, data generated by an untrusted user) typically requires extra care, because even the smallest mistake in the use of `tar` is more likely to be exploited by an adversary than by a race condition.
