Flash (Alert)


Abstract

Notice of security vulnerabilities which impact IBM Rational RequisiteWeb (RequisiteWeb) along with instructions to resolve the issues.

Content

Security vulnerabilities which impacts both RequisiteWeb version 7.1.2 and 7.1.3 clients:

1. PKCS#12 Trust Anchor Insertion Vulnerability (CVE-2012-2203)

2. GSKit Encrypted Record Length Vulnerability (CVE-2012-2191)


Vulnerabilities:

CVE ID: CVE-2012-2203
Description:
IBM Global Security Kit (GSKit) versions before 8.0.14.22, used in IBM Rational RequisiteWeb and other products, use the PKCS #12 file format for certificate objects without enforcing file integrity. This makes it easier for remote attackers to spoof Secure Sockets Layer (SSL) servers.

CVSS:

CVSS Base Score: 5.8

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/77280 for the current score.

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)

CVE ID: CVE-2012-2191
Description:
IBM Global Security Kit (GSKit) versions before 8.0.14.22, used in RequisiteWeb and other products, do not properly validate data, which allows remote attackers to cause a denial of service (application crash) via crafted values in the Transport Layer Security (TLS) Record Layer, a different vulnerability than CVE-2012-2333.

CVSS:

CVSS Base Score: 5

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/75996 for the current score.

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

REMEDIATION: A GSKit version with the fixes for these vulnerabilities has been implemented in RequisiteWeb versions 7.1.2.8 and 7.1.3.4. Upgrade your software to one of those versions.
