Security Bulletin: Vulnerability in Mozilla Network Security Services (NSS) affects the IBM FlashSystem model V840


## Summary There is a vulnerability in Mozilla NSS to which the IBM® FlashSystem™ V840 is susceptible. An exploit of this vulnerability (CVE-2016-9074) could make the system susceptible to timing side-channel attacks which could be leveraged to allow launch of further attacks on the system ## Vulnerability Details **CVEID:** [_CVE-2016-9074_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-9074>) **DESCRIPTION:** Mozilla Network Security Services (NSS), as used in Mozilla Firefox, could provide weaker than expected security, caused by an insufficient mitigation of timing side-channel attacks. An attacker could exploit this vulnerability to gain launch further attacks on the system.

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.
