Security Bulletin


Summary

Vulnerabilities have been addressed in the GSKit component of IBM Rational ClearQuest.

Vulnerability Details

CVEID: CVE-2016-0702
DESCRIPTION:
OpenSSL could allow a local attacker to obtain sensitive information, caused by a side-channel attack against a system based on the Intel Sandy-Bridge microarchitecture. An attacker could exploit this vulnerability to recover RSA keys.
CVSS Base Score: 2.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111144 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-1447
DESCRIPTION:
The GSKit CMS KDB logic fails to salt the hash function resulting in weaker than expected protection of passwords. A weak password may be recovered. Note: After update the customer should change password to ensure the new password is stored more securely. Products should encourage customers to take this step as a high priority action.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/139972 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2018-1427
DESCRIPTION:
IBM GSKit contains several environment variables that a local attacker could overflow and cause a denial of service.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/139072 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2016-0705
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a double-free error when parsing DSA private keys. An attacker could exploit this vulnerability to corrupt memory and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111140 for the current score
CVSS Environmental Score*: Undefined

Remediation/Fixes

Note: After applying the fixes as noted below, please refer to this document http://publib.boulder.ibm.com/httpserv/ihsdiag/restash.html for information concerning password re-stashing. It is advised that you re-stash your password due to CVE-2018-1447 after you apply the fixes.

The solution is to upgrade to a newer fix pack or release of ClearQuest, and to apply fixes for IBM HTTP Server (IHS).

Affected Versions
Fixes
9.0.1 through 9.0.1.2
9.0 through 9.0.0.6
Install Rational ClearQuest Fix Pack 3 (9.0.1.3) for 9.0.1

8.0 through 8.0.0.21
Install Rational ClearQuest Fix Pack 17 (8.0.1.17) for 8.0.1

ClearQuest CM Server:
Apply an IHS fix for the issue:
  1. Determine the IHS version used by your ClearQuest CM server. Navigate to the IBM HTTP Server installation directory (typically /opt/ibm/HTTPServer or C:\Program Files (x86)\IBM\HTTPServer), then execute the script: bin/versionInfo.sh (UNIX) or bin\versionInfo.bat (Windows). The output includes a section "IBM HTTP Server for WebSphere Application Server". Make note of the version listed in this section.
  2. Review the following IHS security bulletin for the available fixes: Security Bulletin: Multiple vulnerabilities GSKit bundled with IBM HTTP Server. Note: there may be newer security fixes for IBM HTTP Server. Follow the link above (in the section "Get Notified about Future Security Bulletins") to subscribe to WebSphere product support alerts for additional security fixes.
  3. Apply the relevant fixes to your IBM HTTP Server installation used on your ClearQuest CM server host. No ClearQuest-specific steps are necessary

For 7.0, 7.1, 8.0, and earlier releases, IBM recommends upgrading to a fixed, supported version/release/platform of the product.
