+++ This bug was initially created as a clone of Bug #194075 +++

CVE-2007-4849:
  JFFS2, as used on One Laptop Per Child (OLPC) build 542 and possibly
  other Linux systems, when POSIX ACL support is enabled, does not
  properly store permissions during (1) inode creation or (2) ACL
  setting, which might allow local users to access restricted files
  or directories after a remount of a filesystem, related to "legacy
  modes" and an inconsistency between dentry permissions and inode
  permissions.
