Vulnerability Details CVEID: CVE-2015-1788 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when processing an ECParameters structure over a specially crafted binary polynomial field. A remote attacker could exploit this vulnerability to cause the application to enter into an infinite loop. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103778 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-1789 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read in X509_cmp_time. An attacker could exploit this vulnerability using a specially crafted certificate or CRL to trigger a segmentation fault. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103779 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-1790 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the improper handling of missing inner EncryptedContent by the PKCS#7 parsing code. An attacker could exploit this vulnerability using specially crafted ASN.1-encoded PKCS#7 blobs with missing content to trigger a NULL pointer dereference. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103780 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-1791 DESCRIPTION: A double-free memory error in OpenSSL in the ssl3_get_new_session_ticket() function has an unknown impact. By returning a specially crafted NewSessionTicket message, an attacker could cause the client to reuse a previous ticket resulting in a race condition. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103609 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N) CVEID: CVE-2015-1792 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when verifying a signedData message. An attacker could exploit this vulnerability using an unknown hash function OID to cause the application to enter into an infinite loop. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103781 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) Affected Products and Versions IBM PredictiveInsight v8.0 - v9.0 Remediation/Fixes Customers using IBM Predictive Insight are recommended to contact Technical Support team for further guidance.
