internal/cimxml/sax/NodeFactory.java in Standards-Based Linux Instrumentation for Manageability (SBLIM) Common Information Model (CIM) Client (aka sblim-cim-client2) before 2.1.12 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML file.

This update of sblim-cim-client2 fixed a Denial of Service (via hash table collision) issue.

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2012-0987 advisory.

    [2.1.3-2]
    - Fix possible XML Hash DoS       Resolves: #803391

    [2.1.3]
    - Update to sblim-cim-client2-2.1.3

    [2.0.9.2-1]
    - Initial support

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The SBLIM (Standards-Based Linux Instrumentation for Manageability) CIM (Common Information Model) Client is a class library for Java applications that provides access to CIM servers using the CIM Operations over HTTP protocol defined by the DMTF (Distributed Management Task Force) standards.

It was found that the Java HashMap implementation was susceptible to predictable hash collisions. SBLIM uses HashMap when parsing XML inputs. A specially crafted CIM-XML message from a WBEM (Web-Based Enterprise Management) server could cause a SBLIM client to use an excessive amount of CPU. Randomization has been added to help avoid collisions. (CVE-2012-2328)

All users of sblim-cim-client2 are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue.

Updated sblim-cim-client2 packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
