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.

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.

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 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.

Multiple buffer overflows in IBM Rational ClearCase 7.x before 7.1.2.13, 8.0.0.x before 8.0.0.10, and 8.0.1.x before 8.0.1.3 allow remote authenticated users to obtain privileged access via unspecified vectors.

The Web Client in IBM Rational ClearQuest 7.1 through 7.1.2.12, 8.0.0.x before 8.0.0.9, and 8.0.1.x before 8.0.1.2, when a multi-database dataset exists, allows remote attackers to read database names via unspecified vectors.

Buffer overflow in IBM Rational ClearCase through 7.1.2.12, 8.0.0.x before 8.0.0.9, and 8.0.1.x before 8.0.1.2 allows local users to gain privileges via unspecified vectors.

Unspecified vulnerability in IBM Rational ClearCase through 7.1.2.12, 8.0.0.x before 8.0.0.9, and 8.0.1.x before 8.0.1.2 allows local users to gain privileges via unknown vectors.
