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.
