RHSA-2012:0987 - Low: sblim-cim-client2 security update

Synopsis

Low: sblim-cim-client2 security update

Type/Severity

Security Advisory Low

Topic

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.

Description

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.
