Description
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to an error when handling HSTS long file names. When saving HSTS data to an excessively long file name, curl can end
up removing all contents from the file, making subsequent requests using that file
unaware of the HSTS status they should otherwise use. As a result, a remote attacker can perform MitM attack.
Remediation
Install updates from vendor's website.
