3. Description:

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

Red Hat Enterprise Linux 7: RHSA-2017-3260-01 Important Samba Fix

red hat
Calendar Grey November 27, 2017
Dist Redhat Esm H88
Crucial samba security patch for Red Hat Enterprise Linux addresses serious vulnerabilities from potential attack vectors.
An update for samba is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing this update, the smb service will be restarted automatically.

Summary

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