Summary: Updated samba packages that fix one security issue and one bug are now available for Red Hat Gluster Storage 3.1 for Red Hat Enterprise Linux 6 and 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Gluster 3 Samba on RHEL-6 - noarch, x86_64 Red Hat Gluster 3 Samba on RHEL-7 - noarch, x86_64 3. Description: 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
