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
DESCRIPTION: OpenSSL could allow a local attacker to bypass security restrictions, caused by the building of . mingw programs or Windows programs with world writable path defaults. An attacker could exploit this vulnerability to modify default configuration, insert CA certificates, modify (or even replace) existing engine modules.
CVSS Base Score: 2.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/164498 for the current score.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a padding oracle attack in PKCS7_dataDecode and CMS_decrypt_set1_pkey. By sending an overly large number of messages to be decrypted, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/167022 for the current score.
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)

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
Apply a fix pack as listed in the table below. The fix pack includes OpenSSL 1.0.2r.
