Notice of security vulnerabilities which impact IBM Rational RequisiteWeb
(RequisiteWeb) along with instructions to resolve the issues.
Security vulnerabilities which impacts both RequisiteWeb version 7.1.2 and
1. PKCS#12 Trust Anchor Insertion Vulnerability (CVE-2012-2203)
2. GSKit Encrypted Record Length Vulnerability (CVE-2012-2191)
CVE ID: CVE-2012-2203 Description: IBM Global Security Kit (GSKit) versions
before 22.214.171.124, 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 Base Score: 5.8
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/77280 for the
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 126.96.36.199, 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 Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/75996 for the
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 188.8.131.52 and 184.108.40.206. Upgrade your
software to one of those versions.
None known; upgrade your software to RequisiteWeb version 220.127.116.11 or 18.104.22.168.
