Content

Security vulnerabilities which impacts Rational Directory Server 5.2.x (Tivoli):

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 (aka GSKit) before 8.0.14.22, as used in IBM Rational Directory Server, IBM Rational Change, IBM Rational DOORS, IBM Rational Synergy, and other products, uses the PKCS #12 file format for certificate objects without enforcing file integrity, which makes it easier for remote attackers to spoof 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)
