libcurl can be told to save cookie, HSTS and/or alt-svc data to files. When doing this, it called `stat()` followed by `fopen()` in a way that made it vulnerable to a TOCTOU race condition problem. By exploiting this flaw, an attacker could trick the victim to create or overwrite protected files holding this data in ways it was not intended to.

Rejected reason: We issued this CVE pre-maturely, as we have subsequently realized that this issue points out a problem that there really is no safe measures around or protections for.

A flaw was found in the curl package. This race condition modifies the behavior of symbolic link files in affected components which might be followed instead of overwritten when the condition is met, leading to undesired and potentially destructive behavior.
