Description

## Summary Security vulnerabilities have been discovered in GNU Bash, which is used by IBM Security Network Protection. IBM Security Network Protection has addressed the applicable CVEs. ## Vulnerability Details **CVEID:** [_CVE-2016-0634_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-0634>)** DESCRIPTION:** GNU Bash could allow a local attacker to execute arbitrary code on the system, caused by an error related to the expansion of the $HOSTNAME. By injecting the hostname with malicious code, an attacker could exploit this vulnerability to execute arbitrary code on the system. CVSS Base Score: 4.9 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/121373_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/121373>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L) **CVEID:** [_CVE-2016-7543_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-7543>)** DESCRIPTION:** GNU Bash could allow a local attacker to execute arbitrary commands on the system. An attacker could exploit this vulnerability using specially crafted SHELLOPTS and PS4 variables to execute arbitrary commands on the system with root privileges. CVSS Base Score: 8.4 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/121372_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/121372>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) **CVEID:** [_CVE-2016-9401_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-9401>)** DESCRIPTION:** GNU Bash could allow a local attacker to bypass security restrictions, caused by a use-after-free error. An attacker could exploit this vulnerability using a specially crafted address to bypass the restricted shell. CVSS Base Score: 4 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/122314_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/122314>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N) ## Affected Products and Versions IBM Security Network Protection 5.3.1 IBM Security Network Protection 5.3.3 ## Remediation/Fixes _Product_ | _VRMF_| _Remediation/First Fix_ ---|---|--- IBM Security Network Protection| Firmware version 5.3.1| Download Firmware 5.3.1.14 from [IBM Security License Key and Download Center](<https://ibmss.flexnetoperations.com/control/isdl/home>) and upload and install via the Available Updates page of the Local Management Interface.

Customers can evaluate the impact of this vulnerability in their environments by accessing the links in the Reference section of this Security Bulletin. ## Disclaimer According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
