Fixed In Version: curl 7.84.0
Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor.

Description Marian Rehak 2022-06-20 14:06:46 UTC 
When curl saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name. In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended.
