Description


Updated samba packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

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 man-in-the-middle vulnerability was found in the way "connection signing"
was implemented by Samba. A remote attacker could use this flaw to
downgrade an existing Samba client connection and force the use of plain
text. (CVE-2015-5296)

A missing access control flaw was found in Samba. A remote, authenticated
attacker could use this flaw to view the current snapshot on a Samba share,
despite not having DIRECTORY_LIST access rights. (CVE-2015-5299)

An access flaw was found in the way Samba verified symbolic links when
creating new files on a Samba share. A remote attacker could exploit this
flaw to gain access to files outside of Samba's share path. (CVE-2015-5252)

Red Hat would like to thank the Samba project for reporting these issues.
Upstream acknowledges Stefan Metzmacher of the Samba Team and Sernet.de as
the original reporters of CVE-2015-5296, partha@exablox.com as the original
reporter of CVE-2015-5299, Jan "Yenya" Kasprzak and the Computer Systems
Unit team at Faculty of Informatics, Masaryk University as the original
reporters of CVE-2015-5252.

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