Security Bulletin
Summary
IBM Integration Bus Hypervisor Edition V9.0 ship with Red Hat Enterprise Linux (RHEL) Server 6.2 which is vulnerable to CVE-2019-14833, CVE-2019-14847, CVE-2019-10218
Vulnerability Details
CVEID: CVE-2019-14833
DESCRIPTION: A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks.
CVSS Base score: 4.2

CVEID: CVE-2019-10218
DESCRIPTION: A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user.
