Security Bulletin
Summary
Security vulnerabilities have been discovered in OpenSSL that were reported on
August 6th, 2014 by the OpenSSL Project.
SWIFTNet adapters of IBM Sterling B2B Integrator and IBM Sterling File Gateway
use OpenSSL libraries for cryptography, and thus are affected by the following
security vulnerabilities discovered in OpenSSL libraries versions 0.9.8 and
1.0.1.
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.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/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-2014-3511
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.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95162 for more
information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
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.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95164 for more
information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2014-3508
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.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95165 for more
information
CVSS Environmental Score*: Undefined
