Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed on June 11, 2015 by the OpenSSL
Project. OpenSSL is used by IBM Rational RequisitePro. RequisitePro has
addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2015-1788
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
when processing an ECParameters structure over a specially crafted binary
polynomial field. A remote attacker could exploit this vulnerability to cause
the application to enter into an infinite loop.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/103778 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-1789
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an
out-of-bounds read in X509_cmp_time. An attacker could exploit this
vulnerability using a specially crafted certificate or CRL to trigger a
segmentation fault.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/103779 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-1791
DESCRIPTION: A double-free memory error in OpenSSL in the
ssl3_get_new_session_ticket() function has an unknown impact. By returning a
specially crafted NewSessionTicket message, an attacker could cause the client
to reuse a previous ticket resulting in a race condition.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/103609 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)
Affected Products and Versions
IBM Rational RequisitePro versions:
Version Status
7.1.4 through 7.1.4.7 Affected
7.1.3 through 7.1.3.14 Affected
7.1.2 through 7.1.2.17 Affected
7.1.1.x (all versions) Affected
Not all deployments of Rational RequisitePro use OpenSSL in a way that is
affected by these vulnerabilities.
You are vulnerable if your use of Rational RequisitePro includes any of these
configurations:
1. You use SSL connections in perl scripts run by ratlperl or cqperl.
2. You integrate with ClearQuest.
Remediation/Fixes
Affected Versions Prerequisite before applying the fix
7.1.4 through 7.1.4.7 Install Rational RequisitePro Fix Pack 8 (7.1.4.8) for 7.1.4
7.1.3 through 7.1.3.14 Install Rational RequisitePro Fix Pack 15 (7.1.3.15) for 7.1.3
7.1.2.x (all fix packs) Install Rational RequisitePro Fix Pack 18 (7.1.2.18) for 7.1.2. Note: 7.1.2.18
7.1.1.x (all fix packs) interoperates with all 7.1.1.x and 7.1.0.x systems, and can be installed in
7.1.0.x (all fix packs) the same way as 7.1.1.x and 7.1.0.x fix packs.
The fix is to install the latest version of RequisitePro, then contact
Rational Support for instructions to apply the rest of the fix, which contains
an updated version of OpenSSL.
You should verify applying this fix does not cause any compatibility issues.
For unsupported versions, IBM recommends upgrading to a fixed, supported
version/release/platform of the product.
Workarounds and Mitigations
Disable the integrations and any custom defined ratlperl or cqperl scripts
with SSL until you apply the fixes listed above.
