-Subject: Prevent directory chmod race attack.
-
-CVE-2017-6512 is a race condition attack where the chmod() of directories
-that cannot be entered is misused to change the permissions on other
-files or directories on the system. This has been corrected by limiting
-the directory-permission loosening logic to systems where fchmod() is
-supported.
-
-[Backported (whitespace adjustments) to File-Path 2.12 / perl 5.24 by
-Dominic Hargreaves for Debian.]
