Security Bulletin

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.

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)
