Security Bulletin: Network Intrusion Prevention System is affected by multiple OpenSSL vulnerabilities (CVE-2014-3508, CVE-2014-3509, CVE-2014-3505, CVE-2014-3506, CVE-2014-3507, CVE-2014-3510, CVE-2014-3511)

Summary

Security vulnerabilities have been discovered in OpenSSL components used by IBM Security Network Intrusion Prevention System.

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.

The attack does not require local network access or authentication, but some specialized knowledge and techniques are required. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

CVSS:
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/95159 for more information
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.

The attack does not require local network access, authentication, or specialized knowledge and techniques. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

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.

The attack does not require local network access, authentication, or specialized knowledge and techniques. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

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.

The attack does not require local network access or authentication, but some specialized knowledge and techniques are required. An exploit would not affect the availability of the system or confidentiality of information, but it could impact the integrity of data.

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.

The attack does not require local network access, authentication, or specialized knowledge and techniques. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

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.

The attack does not require local network access or authentication, but some specialized knowledge and techniques are required. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

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.

The attack does not require local network access or authentication, but some specialized knowledge and techniques are required. An exploit would not affect the integrity of data or availability of the system, but it could impact the confidentiality of information.
