Summary

There are multiple vulnerabilities in OpenSSL that is used by IBM Flex System Manager (FSM). These issues were disclosed on August 6, 2014 by the OpenSSL Project.

Vulnerability Details

CVE-ID: CVE-2014-3509

Description: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl_parse_serverhello_tlsext() code. If a multithreaded client connects to a malicious server using a resumed session, 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/95159&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3506

Description: OpenSSL is vulnerable to a denial of service, caused by an error when processing DTLS handshake messages. A remote attacker could exploit this vulnerability to consume an overly large amount of memory.

CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95160&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3507

Description: OpenSSL is vulnerable to a denial of service. By sending specially-crafted DTLS packets, a remote attacker could exploit this vulnerability to leak memory and cause a denial of service.

CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95161&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3511

Description: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the negotiation of TLS 1.0 instead of higher protocol versions by the OpenSSL SSL/TLS server code when handling a badly fragmented ClientHello message. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to TLS 1.0.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95162&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-3505

Description: OpenSSL is vulnerable to a denial of service, caused by a double-free error when handling DTLS packets. A remote attacker could exploit this vulnerability to cause the system to crash.

CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95163&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3510

Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in anonymous ECDH ciphersuites. A remote attacker could exploit this vulnerability using a malicious handshake to cause the client to crash.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95164&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3508

Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in OBJ_obj2txt. If applications echo pretty printing output, an attacker could exploit this vulnerability to read information from the stack.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/95165&gt; for current score
CVSS Environmental Score*: Undefined
