Security Bulletin


Summary

IBM Cognos BI Server is affected by multiple security exposures.

Vulnerability Details


CVE ID: CVE-2014-0416


    DESCRIPTION: javax.security.auth.Subject is serializable but does not validate deserialized data properly. Malicious code could exploit this to construct an invalid Subject instance with content that differs from the advertised properties. In addition, if a server deserializes serialized data from untrusted sources, an attacker could insert an invalid instance of Subject class into a server Java process.
    The fix ensures that serialized instances of Subject are deserialized correctly and safely.

    CVSS:
    CVSS Base Score: 5
    CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90349 for the current score.
    CVSS Environmental Score*: Undefined
    CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)


CVE ID: CVE-2014-0423

    DESCRIPTION: The DocumentHandler used by the java.beans.XMLDecoder implementation allows the use of external entities by default. This facilitates a variety of attacks via malicious XML data. The fix ensures that external entities are ignored by java.beans.XMLDecoder

    CVSS:
    CVSS Base Score: 5.5
    CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90340 for the current score.
    CVSS Environmental Score*: Undefined
    CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:P)


CVE ID: CVE-2013-4322

    DESCRIPTION: Apache Tomcat before 6.0.39, 7.x before 7.0.50, and 8.x before 8.0.0-RC10 processes chunked transfer coding without properly handling (1) a large total amount of chunked data or (2) whitespace characters in an HTTP header value within a trailer field, which allows remote attackers to cause a denial of service by streaming data.
    NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3544.

    CVSS:
