Doc Text:
A security bypass flaw was found in Curl, which can be triggered by saving HSTS data to an excessively long file name. This issue occurs due to an error in handling HSTS long file names, leading to the removal of all contents from the file during the save process, and may allow a remote attacker to send a specially crafted request to use files without awareness of the HSTS status and enable a Man-in-the-Middle (MitM) attack.

Description Marian Rehak 2023-11-29 06:18:05 UTC 
When saving HSTS data to an excessively long file name, curl could end up removing all contents, making subsequent requests using that file unaware of the HSTS status they should otherwise use. The reason for this bug is that save function appended a suffix to the file name, created a temporary file and then in the last step renamed that to the final name. When the file name length was close to the limit of what is allowed on the file system, adding the extension would make it too long and then trigger this bug.
