Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL
Project. OpenSSL is used by the Cordova platform packaged with Rational
Software Architect and Rational Software Architect for WebSphere Software and
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 http://xforce.iss.net/xforce/xfdb/99710 for 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 http://xforce.iss.net/xforce/xfdb/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 http://xforce.iss.net/xforce/xfdb/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 http://xforce.iss.net/xforce/xfdb/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: OpenSSL could provide weaker than expected security. The client
accepts the use of an RSA temporary key in a non-export RSA key exchange
ciphersuite. An attacker could exploit this vulnerability to launch further
attacks on the system.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99707 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/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 http://xforce.iss.net/xforce/xfdb/99708 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:S/C:N/I:P/A:N)
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 http://xforce.iss.net/xforce/xfdb/99704 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
