The Remote Client and change management integrations in IBM Rational ClearCase 7.1.x, 8.0.0.x before 8.0.0.18, and 8.0.1.x before 8.0.1.11 do not properly validate hostnames in X.509 certificates from SSL servers, which allows remote attackers to spoof servers and obtain sensitive information or modify network traffic via a crafted certificate. IBM X-Force ID: 106715.

The MSCAPI/MSCNG interface implementation in GSKit in IBM Rational ClearCase 7.1.2.x before 7.1.2.17, 8.0.0.x before 8.0.0.14, and 8.0.1.x before 8.0.1.7 does not properly generate random numbers, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors.

IBM Rational ClearCase 8.0.0 before 8.0.0.14 and 8.0.1 before 8.0.1.7, when Installation Manager before 1.8.2 is used, retains cleartext server passwords in process memory throughout the installation procedure, which might allow local users to obtain sensitive information by leveraging access to the installation account.

IBM Rational ClearQuest 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 does not properly implement the Local Access Only protection mechanism, which allows remote attackers to bypass authentication and read files via the Help Server Administration feature.

The OSLC integration feature in the Web component in IBM Rational ClearQuest 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 provides different error messages for failed login attempts depending on whether the username exists, which allows remote attackers to enumerate account names via a series of requests.

IBM Rational ClearQuest 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.

The Web component in IBM Rational ClearQuest 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 does not set the secure flag for the session cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

The login form in the Web component in IBM Rational ClearQuest 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 does not insert a delay after a failed authentication attempt, which makes it easier for remote attackers to obtain access via a brute-force attack.

IBM Rational ClearCase 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.
