Overview
Affected versions of this package are vulnerable to UNIX Symbolic Link (Symlink) Following through the use of a predictable temporary file path in the screenshot handling process. An attacker can cause truncation and ownership changes of arbitrary files by pre-placing symlinks in the /tmp directory before a screenshot is requested. This is only exploitable if the kernel's protected_symlinks feature is disabled (i.e., /proc/sys/fs/protected_symlinks is set to 0).
