RHEL 6 : samba (RHSA-2019:4023)

critical Nessus Plugin ID 131525

Language:

Synopsis

The remote Red Hat host is missing a security update for samba.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:4023 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL samba package based on the guidance in RHSA-2019:4023.
