Security Bulletin: Seven (7) Vulnerabilities in OpenSSL affect IBM FlashSystem 840 and V840 (CVEs)

Security Bulletin


Summary

OpenSSL vulnerabilities affect the IBM FlashSystem 840 and V840 products. These vulnerabilities could allow a remote attacker to execute arbitrary code on the system, to obtain sensitive information, or cause of denial of service.

Vulnerability Details

1. 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)

2. CVE-ID: CVE-2014-3506
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when processing DTLS handshake messages. A remote attacker could exploit this vulnerability to consume an overly large amount of memory.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95160 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

3. CVE-ID: CVE-2014-3507
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending specially-crafted DTLS packets, a remote attacker could exploit this vulnerability to leak memory and cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95161 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

4. 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)

5. CVE-ID: CVE-2014-3505
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a double-free error when handling DTLS packets. A remote attacker could exploit this vulnerability to cause the system to crash.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95163 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

6. 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)

7. 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
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

Remediation/Fixes

IBM recommends that you fix this vulnerability by promptly upgrading affected versions of IBM FlashSystem 840 and V840 systems to the following code level or higher:

for 840 & V840 machine types 9840, 9846, & 9848, –AE1 models: 1.1.2.7
for V840 machine types 9846 & 9848, –AC0 & -AC1 models: 7.3.0.7

In addition, IBM recommends that you review your entire environment to identify vulnerable releases of OpenSSL in other (e.g. non-IBM products and versions) including in your Operating Systems and take appropriate mitigation and remediation actions. Please contact your Operating System provider for more information.
