Synopsis
Moderate: samba security, bug fix, and enhancement update
Type/Severity
Security Advisory Moderate
Topic
An update for samba is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
The following packages have been upgraded to a later upstream version: samba (4.10.4). (BZ#1724991)
Security Fix(es):
-
samba: Combination of parameters and permissions can allow user to escape from the share path definition (CVE-2019-10197)
-
samba: smb client vulnerable to filenames containing path separators (CVE-2019-10218)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
