Type/Severity
Security Advisory: Important
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An update for samba is now available for Red Hat Gluster Storage 3.3 for Red Hat Enterprise Linux 6 and Red Hat Gluster Storage 3.3 for Red Hat Enterprise Linux 7.
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.
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.
