CVE-ID: CVE-2014-5139
Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when an SRP ciphersuite is specified without being properly negotiated with the client. A remote attacker could exploit this vulnerability to cause the client to crash.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/95166 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2014-3511
Description: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the negotiation of TLS 1.0 instead of higher protocol versions by the OpenSSL SSL/TLS server code when handling a badly fragmented ClientHello message. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to TLS 1.0.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/95162 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-3509
Description: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl_parse_serverhello_tlsext() code. If a multithreaded client connects to a malicious server using a resumed session, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/95159 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
Affected Products and Versions
IBM Rational ClearCase versions:
Version | Status |
8.0.1 through 8.0.1.5 | Affected |
8.0 through 8.0.0.12 | Affected |
7.1.0.x, 7.1.1.x, 7.1.2.x (all versions) | Affected |
7.0.x | Not affected |
Not all deployments of Rational ClearCase use OpenSSL in a way that is affected by these vulnerabilities.
You are vulnerable if your use of Rational ClearCase includes any of these configurations:
- You use the base ClearCase/ClearQuest integration client on any platform, configured to use SSL to communicate with a ClearQuest server.
- You use the UCM/ClearQuest integration on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest server.
Note: Windows clients using the UCM/ClearQuest integration are not vulnerable.
- You use the Change Management Integrations for base ClearCase with ClearQuest or Rational Team Concert (RTC), or for UCM with ClearQuest or RTC on UNIX/Linux clients, configured to use SSL to communicate with a ClearQuest or RTC server.
Note: Windows clients using the CMI integration are not vulnerable.
- You use ratlperl, ccperl, or cqperl to run your own perl scripts, and those scripts use SSL connections.
Remediation/Fixes
Apply a fix pack for your appropriate release of ClearCase. These fix packs include OpenSSL 1.0.1i.
Affected Versions | Applying the fix |
8.0.1.x | Install Rational ClearCase Fix Pack 6 (8.0.1.6) |
8.0.0.x | Install Rational ClearCase Fix Pack 13 (8.0.0.13) |
7.1.2.x 7.1.1.x 7.1.0.x | Customers with extended support contracts should install Rational ClearCase Fix Pack 16 (7.1.2.16) |
Workarounds and Mitigations
Disable the ClearCase/ClearQuest integration and any customized defined use of ratlperl, ccperl, or cqperl with SSL until you apply the fixes listed above.
