Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL is used by IBM Rational ClearCase. IBM Rational ClearCase has addressed the applicable CVE.
Vulnerability Details
CVEID: CVE-2019-1551
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an overflow in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. By performing a man-in-the-middle attack, a remote attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 6.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/172752 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N)
Affected Products and Versions
| Affected Product(s) | Version(s) |
| IBM Rational ClearCase | 8.0.0 |
| IBM Rational ClearCase | 9.0 |
| IBM Rational ClearCase | 9.0.1 |
| IBM Rational ClearCase | 9.0.2 |
| IBM Rational ClearCase | 8.0.1 |
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. - On UNIX/Linux clients, you use the Change Management Integration (CMI), when configured to use SSL to communicate with the 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
