OpenSSL is used by IBM PureApplication System. IBM PureApplication System has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2015-0209 DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free error in the d2i_ECPrivateKey or EVP_PKCS82PKEY function. An attacker could exploit this vulnerability using a malformed Elliptic Curve (EC) private-key file to corrupt memory and execute arbitrary code on the system and cause a denial of service. CVSS Base Score: 6.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101674 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P) CVEID: CVE-2015-0286 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error in the ASN1_TYPE_cmp function when attempting to compare ASN.1 boolean types. An attacker could exploit this vulnerability to crash any certificate verification operation and cause a denial of service. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101666 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-0287 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error related to the reuse of a structure in ASN.1 parsing. An attacker could exploit this vulnerability using an invalid write to corrupt memory and cause a denial of service. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101668 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-0288 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error in the X509_to_X509_REQ function. An attacker could exploit this vulnerability to trigger a NULL pointer dereference. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101675 or the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-0289 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the failure to properly handle missing outer ContentInfo by the PKCS#7 parsing code. An attacker could exploit this vulnerability using a malformed ASN.1-encoded PKCS#7 blob to trigger a NULL pointer dereference. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101669 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-0292 DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by an error when processing base64 encoded data. An attacker could exploit this vulnerability using specially-crafted base 64 data to corrupt memory and execute arbitrary code on the system and cause a denial of service. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101670 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P) CVEID: CVE-2015-0293 DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending a specially-crafted SSLv2 CLIENT-MASTER-KEY message, a remote attacker could exploit this vulnerability to trigger an assertion. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101671 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 PureApplication System V1.0 IBM PureApplication System V1.1 IBM PureApplication System V2.0 IBM PureApplication System V2.1 Remediation/Fixes The solution is to upgrade the IBM PureApplication System to the following fix level: IBM PureApplication System V2.1 Upgrade to IBM PureApplication System V2.1.0.1 IBM PureApplication System V2.0 Upgrade to IBM PureApplication System V2.0.0.1 Interim Fix 4 IBM PureApplication System V1.1 and earlier: Contact IBM customer support for upgrade options.
