Overview

Affected versions of this package are vulnerable to Race Condition due to a race condition during symlink resolution. An attacker can cause a buffer to be smaller than necessary by exploiting the timing of the readlink operation. This is only exploitable on Unix-based operating systems such as Android, Linux, and MacOS; Windows systems are not affected.
