Summary
Security vulnerabilities have been discovered in the OpenSSL libraries used by
IBM Sterling B2B Integrator and IBM Sterling File Gateway.
Vulnerability Details
CVE ID: 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
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)
CVE ID: 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)
CVE ID: 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)
CVE ID: 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)
CVE ID: 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)
CVE ID: 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: 1.2
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99707 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)
CVE ID: 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)
CVE ID: 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)
