The fix adds a new check to prevent the attack. This issue affects any application that uses the JSSE implementation of Diffie-Helman key exchange, either directly or via protocols such as SSL or TLS. The vulnerability applies to both client and server usage. CVSS Base Score: 4 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/94606 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N) CVE-2014-4244: If an attacker can observe local variables (temperature, RF, sound), they can deduce the RSA private key based on changes in those variables. The fix introduces "dead" computations (aka blinding) to foil these attacks. This issue affects applications which use the RSA encryption algorithm, but it is only exploitable by a local user with direct access to the environment on which the JRE is running. CVSS Base Score: 4 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/94605 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N) CVE-2015-0410: A flaw in the ASN.1 parser allows an attacker to induce an infinite loop by passing in malicious data (a well chosen negative integer). CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100151 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVE-2014-6593: A flaw in the TLS implementation involving the tracking of ChangeCipherSpec messages allows a man-in-the-middle attacker to force the connection into plaintext. CVSS Base Score: 4 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100153 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N) Affected Products and Versions IBM WebSphere MQ Telemetry 7.0.1 Remediation/Fixes REMEDIATION A fix for the IBM WebSphere MQ Telemetry 7.0.1 is available from IBM by requesting IT04335 from IBM Support.
