CVE ID: CVE-2014-0075

Description: Apache Tomcat is vulnerable to a denial of service, caused by the improper handling of a malformed chunk size as part of a chunked request. A remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 5 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/93365&gt; for the current score *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE ID: CVE-2014-0096

Description: Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by an XML External Entity Injection (XXE) error when processing XML data by the default server. By sending specially-crafted XML data, an attacker could exploit this vulnerability to obtain sensitive information.

CVSS Base Score: 4.3 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/93367&gt; for the current score *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

CVE ID: CVE-2014-0099

Description: Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by the failure to check for overflows when parsing content length headers. By sending specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information.

CVSS Base Score: 5 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/93369&gt; for the current score *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

CVE ID: CVE-2014-0119

Description: Apache Tomcat could allow a remote attacker to obtain sensitive information, caused by the replacement of the XML parsers used to process XSLTs for the default servlet. An attacker could exploit this vulnerability using a specially-crafted application to obtain sensitive information.

CVSS Base Score: 5 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/93368&gt; for the current score *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

Affected Products and Versions

Rational Test Control Panel component in Rational Test Virtualization Server and Rational Test Workbench versions:

• All 8.0.x
• All 8.5.0.x

Versions 8.5.1 and later are unaffected as they do not use Apache Tomcat.

Remediation/Fixes

The fixes for the CVEs mentioned above have been incorporated into the 7.0.54 release of Apache Tomcat. You should upgrade your installation by following the instructions below.

1. Download the fix for your product from Fix Central:

• Rational Test Workbench - 7.0.54-Rational-RTW-Tomcat-zip

• Rational Test Virtualization Server - 7.0.54-Rational-RTVS-Tomcat-zip
  

• Unzip the downloaded file to a directory.

• Stop the server.

• In the existing RTCP installation, save the files logging.properties and server.xml to a separate location.

The default installation locations for these files are:

• Windows: C:\Program Files\IBM\RationalTestControlPanel\conf\
• AIX, Linux, Solaris: `/opt/IBM/RationalTestControlPanel/conf/

`

• Copy the contents of the unzipped Tomcat directory (except for the LICENSE file) into the RationalTestControlPanel directory, overwriting the existing files.

• Copy the two configuration files you saved earlier back into /conf.

• Start the server.

Notes:

• When updating an installation to a later version of Rational Test Control Panel, the security fix detailed above will have to be re-applied after the RTCP update
• When removing an installation that has had the security fix applied, not all the files will be removed by IBM Installation Manager, and some files will have to be removed manually.
