CVE-2025-0913 Information

Description

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.
