Inconsistent handling of O_CREATE|O_EXCL on Unix and Windows… (CVE-2025-0913)

Summary

Inconsistent handling of O_CREATE|O_EXCL on Unix and Windows in os in syscall

Original description

The description as published by the source.

os.OpenFile(path, os.O_CREATE|O_EXCL) behaved differently on Unix and Windows systems when the target path was a dangling symlink. On Unix systems, OpenFile with O_CREATE and O_EXCL flags never follows symlinks. On Windows, when the target path was a symlink to a nonexistent location, OpenFile would create a file in that location. OpenFile now always returns an error when the O_CREATE and O_EXCL flags are both set and the target path is a symlink.
