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 Sterling
Connect:Enterprise for UNIX. Sterling Connect:Enterprise for UNIX 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
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-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 http://xforce.iss.net/xforce/xfdb/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-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-2014-3572
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)
