Vulnerability Vulnerable Version

Vulnerability	Vulnerable Version
M Improper Handling of Unicode Encoding tar is a full-featured Tar for Node.js. Affected versions of this package are vulnerable to Improper Handling of Unicode Encoding in Path Reservations via Unicode Sharp-S (`ß`) Collisions on macOS APFS. An attacker can overwrite arbitrary files by exploiting Unicode normalization collisions in filenames within a malicious tar archive on case-insensitive or normalization-insensitive filesystems. Note: This is only exploitable if the system is running on a filesystem such as macOS APFS or HFS+ that ignores Unicode normalization. How to fix Improper Handling of Unicode Encoding? Upgrade `tar` to version 7.5.4 or higher.	<7.5.4
M Uncontrolled Resource Consumption ('Resource Exhaustion') tar is a full-featured Tar for Node.js. Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') due to the lack of folders count validation during the folder creation process. An attacker who generates a large number of sub-folders can consume memory on the system running the software and even crash the client within few seconds of running it using a path with too many sub-folders inside. How to fix Uncontrolled Resource Consumption ('Resource Exhaustion')? Upgrade `tar` to version 6.2.1 or higher.	<6.2.1
