OpenSSL is used by IBM Predictive Insight. IBM Predictive Insight has addressed the applicable CVEs including the DROWN: Decrypting RSA with Obsolete and Weakened eNcryption" vulnerability. Vulnerability Details CVEID: CVE-2016-0800 DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions. By using a server that supports SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle, an attacker could exploit this vulnerability to decrypt TLS sessions between clients and non-vulnerable servers. This vulnerability is also known as the DROWN attack. CVSS Base Score: 7.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111139 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) CVEID: CVE-2016-0705 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a double-free error when parsing DSA private keys. An attacker could exploit this vulnerability to corrupt memory and cause a denial of service. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111140 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2016-0798 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak in SRP servers. An attacker could exploit this vulnerability using a specially crafted username value to cause a denial of service. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111141 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2016-0797 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the BN_hex2bn/BN_dec2bn() function. An attacker could exploit this vulnerability using specially crafted data to cause a denial of service. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111142 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2016-0799 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a memory error in the BIO_*printf() functions. An attacker could exploit this vulnerability using specially crafted data to trigger an out-of-bounds read. CVSS Base Score: 3.7 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111143 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2016-0702 DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by a side-channel attack against a system based on the Intel Sandy-Bridge microarchitecture. An attacker could exploit this vulnerability to recover RSA keys. CVSS Base Score: 2.9 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111144 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:N/A:N) CVEID: CVE-2016-0703 DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the failure to enforce that a clear-key-length value is 0 for non-export ciphers by the SSLv2 's2_srvr.c code. When clear-key bytes displace encrypted-key bytes, an attacker could exploit this vulnerability to conduct a divide-and-conquer key recovery attack. CVSS Base Score: 7.4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111145 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) CVEID: CVE-2016-0704 DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions. The s2_srvr.c code overwrites the wrong bytes in the master-key when applying Bleichenbacher protection for export cipher suites. An attacker could exploit this vulnerability using a Bleichenbacher oracle to decrypt sessions. CVSS Base Score: 5.9 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111146 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N) CVEID: CVE-2016-2842 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the failure to verify that a certain memory allocation succeeds by the doapr_outch function. A remote attacker could exploit this vulnerability using a specially crafted string to cause an out-of-bounds write or consume an overly large amount of resources. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111304 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) Affected Products and Versions IBM Predictive Insight 8.5 - 9.0 Remediation/Fixes Customers using IBM Predictive Insight are recommended to contact Technical Support team for further guidance. IBM recommends that the same certificate should ONLY be shared with identical server configuration and software. If the same certificate were shared with different server(s) configuration or software, IBM recommends replacing the different server(s) with unique certificates to protect against the DROWN exposure. Workarounds and Mitigations IBM Predictive Insight customers can mitigate the risk by allowing only white-listed IPs to access the application.
