Red Hat Security Advisory
Synopsis: Important: samba4 security update
Advisory ID: RHSA-2017:3278-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:3278
Issue date: 2017-11-29
CVE Names: CVE-2017-14746 CVE-2017-15275
=====================================================================
1. Summary:
An update for samba4 is now available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, 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.
Security Fix(es):
* A use-after-free flaw was found in the way samba servers handled certain
SMB1 requests. An unauthenticated attacker could send specially-crafted
SMB1 requests to cause the server to crash or execute arbitrary code.
(CVE-2017-14746)
* A memory disclosure flaw was found in samba. An attacker could retrieve
parts of server memory, which could contain potentially sensitive data, by
sending specially-crafted requests to the samba server. (CVE-2017-15275)
Red Hat would like to thank the Samba project for reporting these issues.
Upstream acknowledges Yihan Lian and Zhibin Hu (Qihoo 360 GearTeam) as the
original reporter of CVE-2017-14746; and Volker Lendecke (SerNet and the
Samba Team) as the original reporter of CVE-2017-15275.
