Security Bulletin

Summary

OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL 
Project. This includes FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL 
client and server vulnerability. OpenSSL is used by IBM Security Network 
Enterprise Scanner. IBM Security Network Enterprise Scanner has addressed the
applicable CVEs.

Vulnerability Details

CVEID:CVE-2014-3569

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the 
failure to properly handle attempts to use unsupported protocols by the 
ssl23_get_client_hello function in s23_srvr.c. A remote attacker could exploit
this vulnerability using an unexpected handshake to trigger a NULL pointer 
dereference and cause the daemon to crash.

CVSS Base Score: 5.0

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99706 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P

CVEID: CVE-2014-3570

DESCRIPTION: An unspecified error in OpenSSL related to the production of 
incorrect results on some platforms by Bignum squaring (BN_sqr) has an unknown
attack vector and impact.

CVSS Base Score: 2.6

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99710 or the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)

CVEID: CVE-2014-3571

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL 
pointer dereference when handling malicious messages. By sending a 
specially-crafted DTLS message, a remote attacker could exploit this 
vulnerability to cause a segmentation fault.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99703 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2014-3572

DESCRIPTION: OpenSSL could provide weaker than expected security. The client 
accepts a handshake using an ephemeral ECDH ciphersuite with the server key 
exchange message omitted. An attacker could exploit this vulnerability to 
launch further attacks on the system.

CVSS Base Score: 1.2

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99705 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)

CVEID: CVE-2014-8275

DESCRIPTION: OpenSSL could allow a local attacker to bypass security 
restrictions, caused by the modification of the fingerprint without breaking 
the signature. An attacker could exploit this vulnerability using non-DER or 
invalid encodings outside the signed portion of a certificate bypass security
restrictions and perform unauthorized actions.

CVSS Base Score: 1.2

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99709 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-0204

DESCRIPTION: A vulnerability in the OpenSSL ssl3_get_key_exchange function 
could allow a remote attacker to downgrade the security of certain TLS 
connections. An OpenSSL client accepts the use of an RSA temporary key in a 
non-export RSA key exchange ciphersuite. This could allow a remote attacker 
using man-in-the-middle techniques to facilitate brute-force decryption of 
TLS/SSL traffic between vulnerable clients and servers.

This vulnerability is also known as the FREAK attack.

CVSS Base Score: 4.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99707 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-0205

DESCRIPTION: OpenSSL could allow a remote authenticated attacker to bypass 
security restrictions, caused by the acceptance of a DH certificate for client
authentication without verification. An attacker could exploit this 
vulnerability to authenticate without the use of a private key.

CVSS Base Score: 2.1

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99708 for the current 
score

CVSS Environmental Score*: Undefined

CVEID: CVE-2015-0206

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory
leak in the dtls1_buffer_record function. By sending repeated DTLS records 
with the same sequence number, a remote attacker could exploit this 
vulnerability to exhaust all available memory resources.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99704 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
