Security Bulletin: OpenSSL vulnerabilities affect IBM Rational Team Concert
More support for: Rational Team Concert
Software version: 5.0.x, 6.0, 6.0.1, 6.0.2, 6.0.3, 6.0.4, 6.0.5, 6.0.6
Operating system(s): Platform Independent
Reference #: 0734065
Modified date: 04 October 2018
OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL is used
by Rational BuildForge Agent shipped with IBM Rational Team Concert. Rational
BuildForge has addressed the applicable CVEs.
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
sending of a very large prime value to the client by a malicious server during
key agreement in a TLS handshake. By spending an unreasonably long period of
time generating a key for this prime, a remote attacker could exploit this
vulnerability to cause the client to hang.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
144658 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
Affected Products and Versions
Rational Collaborative Lifecycle Management 5.0 - 6.0.6
Rational Team Concert 5.0 - 5.0.2
Rational Team Concert 6.0 - 6.0.6
Follow the steps on Security Bulletin: Multiple vulnerabilities in Apache
Tomcat, Open SSL, and Apache HTTPD affects Rational Build Forge to get the
fixed version of Rational Build Forge Agent.
