Security Bulletin
Summary
There are vulnerabilities in Mozilla Network Security Services (NSS) to which the IBM® FlashSystem™ 840 and FlashSystem™ 900 are susceptible. An exploit of these vulnerabilities (CVE-2016-2834, CVE-2016-5285, and CVE-2016-8635) could allow a remote attacker to execute arbitrary code, to recover private keys, to crash a TLS/SSL server, or to cause a denial of service.
Vulnerability Details
CVEID: CVE-2016-2834
DESCRIPTION: Mozilla Network Security Services (NSS), as used in Mozilla Firefox, could allow a remote attacker to execute arbitrary code on the system, caused by memory safety bugs within the browser engine. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using unknown attack vectors to execute arbitrary code on the vulnerable system or cause a denial of service.
CVSS Base Score: 8.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113870 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID: CVE-2016-5285
DESCRIPTION: Mozilla Network Security Services (NSS), as used in Mozilla Firefox, is vulnerable to a denial of service, caused by a NULL pointer dereference in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime when handling invalid Diffie-Hellman keys. A remote attacker could exploit this vulnerability to crash a TLS/SSL server.
CVSS Base Score: 5.3

CVEID: CVE-2016-8635
DESCRIPTION: Mozilla Network Security Services (NSS), as used in Mozilla Firefox, could allow a remote attacker to obtain sensitive information, caused by a small subgroup confinement attack in Diffie Hellman Client key exchange handling. By confining the client DH key to small subgroup of the desired group, a remote attacker could exploit this vulnerability to recover private keys.
