Summary
Potential Security Exposure with IBM WebSphere MQ Telemetry 7.0.1
Vulnerability Details
CVE-2014-4263: The JSSE component's Diffie-Hellman key exchange
implementation is vulnerable to a man-in-the middle attack.
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.
