Samba is an open-source implementation of the Server Message Block (SMB) or
Common Internet File System (CIFS) protocol, which allows PC-compatible
machines to share files, printers, and other information.

A flaw was found in the way Samba handled ACLs on symbolic links.
An authenticated user could use this flaw to gain access to an arbitrary
file or directory by overwriting its ACL. (CVE-2015-7560)

Red Hat would like to thank the Samba project for reporting this issue.
Upstream acknowledges Jeremy Allison (Google) and the Samba team as the
original reporters.

This update also fixes the following bug:

  • Under a high load, the vfs_glusterfs AIO code would hit a use-after-free
    error and cause a crash. This update fixes the affected code, and crashes
    no longer occur. (BZ #1315736)

All samba users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing this
update, the smb service will be restarted automatically.
