OpenSSL issues from March 2015 containing 12 CVE were disclosed. This bulletin addresses the vulnerabilities that have been referred to as Open SSL used by IBM SAN b-type Switches.

Vulnerability Details

CVEID: CVE-2015-0291
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By connecting to a server and renegotiating with an invalid ClientHello signature algorithms extension, an attacker could exploit this vulnerability to trigger a NULL pointer dereference against the server.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101663 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0207
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an implementation error in the DTLSv1_listen function when processing the initial ClientHello. An attacker could exploit this vulnerability to cause a segmentation fault.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101665 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0208
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error in the signature verification routines. By sending an ASN.1 signature using the RSA PSS algorithm and invalid parameters, 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/101667 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0209
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-2015-0285
DESCRIPTION: OpenSSL could provide weaker than expected security, caused by the failure to seed the PRNG. An attacker could exploit this vulnerability using a PRNG with weak entropy to complete a handshake and generate the client random.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101673 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

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)

CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101675 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0289
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-2015-0290
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error in the multiblock implementation. By using a BIO other than a socket BIO for writing, an attacker could exploit this vulnerability to cause a segmentation fault.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101664 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)

CVEID: CVE-2015-1787
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when client auth is used. By sending an empty ClientKeyExchange message, a remote attacker could exploit this vulnerability to trigger a segmentation fault.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101672 for the current score
CVSS Environmental Score*: Undefined
