(RHSA-2019:4023) Moderate: samba security and bug fix update

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

The following packages have been upgraded to a later upstream version: samba (4.9.8). (BZ#1724260)

Security Fix(es):

• samba: Combination of parameters and permissions can allow the user to escape from the share path definition (CVE-2019-10197)

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.

Bug Fix(es):

• The samba packages have been upgraded to upstream version 4.9.8 which provides a number of bug fixes and enhancements over the previous version. (BZ#1724260)

• Previously, CTDB was unable to start due to a missing filesystem directory. In spite of manually creating the directory, CTDB could not function properly due to an incorrect SELinux context. With this update, the rpm package now properly creates the missing directory with the required SELinux context and CTDB starts correctly. (BZ#1772836)

Users of Samba with Red Hat Gluster Storage are advised to upgrade to these updated packages.
