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.
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.
Additional Changes:
