Security Bulletin: OpenSSL Security Issues with Intel® MPSS for use on Intel Xeon Phi PCIe cards sold by IBM (CVE-2014-0076, CVE-2014-0195, CVE-2014-0198, CVE-2014-0221, CVE-2014-0224, CVE-2014-3470 and CVE-2010-5298)

Vulnerability Details

Abstract

This Security Bulletin discusses several security vulnerabilities that affect previous versions of Intel® Manycore Platform Software Stack (Intel® MPSS) for use on Intel Xeon Phi PCIe cards sold by IBM for use with IBM System x servers. Intel's coprocessors are functioning within specification; this is a software implementation issue.

Vulnerability Details:

CVE-ID: CVE-2014-0076

Description: The Montgomery ladder implementation in OpenSSL through 1.0.0l does not ensure that certain swap operations have a constant-time behavior, which makes it easier for local users to obtain ECDSA nonces via a FLUSH+RELOAD cache side-channel attack.

CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91990 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N)

CVE-ID: CVE-2014-0224

Description: OpenSSL is vulnerable to a man-in-the-middle attack, caused by the use of weak keying material in SSL/TLS clients and servers. A remote attacker could exploit this vulnerability using a specially-crafted handshake to conduct man-in-the-middle attacks to decrypt and modify traffic.

CVSS Base Score: 5.8
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93586 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)

CVE-ID: CVE-2014-0221

Description: OpenSSL is vulnerable to a denial of service, caused by a recursion error in the DTLS client. By sending an invalid DTLS handshake, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93587 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-0195

Description: OpenSSL is vulnerable to a buffer overflow. By sending invalid DTLS packet fragments, a remote attacker could exploit this vulnerability to overrun the client or server and execute arbitrary code on a DTLS client or server.

CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93588 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVE-ID: CVE-2014-0198

Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the do_ssl3_write() function. If SSL_MODE_RELEASE_BUFFERS is enabled, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93000 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2010-5298

Description: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl3_read_bytes function. If SSL_MODE_RELEASE_BUFFERS is enabled, an attacker could exploit this vulnerability using an SSL connection in a multithreaded environment to inject data into an SSL stream and cause a denial of service.

CVSS Base Score: 4
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92632 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:P)

CVE-ID: CVE-2014-3470

Description: OpenSSL is vulnerable to a denial of service, caused by the implementation of anonymous ECDH ciphersuites. A remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/93589 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
