Summary

Multiple vulnerabilities have been identified in openssh that is embedded in the FSM. This bulletin addresses these vulnerabilities.

Vulnerability Details

CVEID: CVE-2016-10011**
DESCRIPTION:** OpenSSH could allow a local authenticated attacker to obtain sensitive information, caused by a privilege separation flaw. An attacker could exploit this vulnerability to obtain host private key material and other sensitive information.
CVSS Base Score: 5.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119830 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2016-10009**
DESCRIPTION:** OpenSSH could allow a remote authenticated attacker to execute arbitrary code on the system, caused by the loading of a specially crafted PKCS#11 module across a forwarded agent channel. An attacker could exploit this vulnerability to write files or execute arbitrary code on the system.
CVSS Base Score: 6.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119828 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2016-6515**
DESCRIPTION:** OpenSSH is vulnerable to a denial of service, caused by the failure to limit password lengths for password authentication by the auth_password function. A remote attacker could exploit this vulnerability using an overly long string to consume all available CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/115911 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2016-6210**
DESCRIPTION:** OpenSSH could allow a remote attacker to obtain sensitive information, caused by the increased amount of time to calculate SHA256/SHA512 hash than BLOWFISH hash. An attacker could exploit this vulnerability using a covert timing channel to enumerate users on system that runs SSHD.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/115128 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

Remediation/Fixes

IBM recommends updating the FSM and all affected remote Common Agent Services (CAS) endpoints using the instructions referenced in this table.

Product VRMF Remediation
Flex System Manager 1.3.4.0
1.3.4.1 Navigate to the Support Portal_ _and search for technote 834644694 for instructions on installing updates for FSM version 1.3.4 and Agents.
Flex System Manager 1.3.3.0
1.3.3.1 Navigate to the Support Portal_ _and search for technote 834644694 for instructions on installing updates for FSM version 1.3.3 and Agents.
Flex System Manager 1.3.2.0
1.3.2.1
1.3.2.2 Navigate to the Support Portal_ _and search for technote 834644694 for instructions on installing updates for FSM version 1.3.2 and Agents.

For all other VRMF IBM recommends upgrading to a fixed, supported version/release of the product.

Note: Installation of the fixes provided in the technote will install a cumulative fix package that will update the version of the FSM. Reference the technote for more details.

You should verify applying this fix does not cause any compatibility issues. The fix may disable older encrypted protocols by default.

IBM recommends that you review your entire environment to identify other areas where you have enabled weak encryption and take appropriate mitigation and remediation actions.
