Security Bulletin: Vulnerabilities in OpenSSL affects IBM PureApplication System (CVE-2015-0209, CVE-2015-0286, CVE-2015-0287, CVE-2015-0288, CVE-2015-0289, CVE-2015-0292, and CVE-2015-0293)

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 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 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
