IBM Security Access Manager appliances use NSS and are affected by these vulnerabilities. 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 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119189 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:L) 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.
