Stefan Metzmacher and Michael Adam discovered that Samba incorrectly
handled DCE-RPC fragment length fields. A remote attacker could use this
issue to cause Samba to crash, resulting in a denial of service, or
possibly execute arbitrary code as the root user. (CVE-2013-4408)

Hemanth Thummala discovered that Samba incorrectly handled file
permissions when vfs_streams_depot or vfs_streams_xattr were enabled. A
remote attacker could use this issue to bypass intended restrictions.
