RHSA-2014:0559 - Security Advisory

Topic

An updated rhevm-dwh package that fixes one security issue and two bugs is
now available.

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 Red Hat Enterprise Virtualization Manager data warehouse package
provides the Extract-Transform-Load (ETL) process and database scripts to
create a historic database API. It also provides SQL BI reports creation
for management and monitoring.

It was found that the ovirt-engine-dwh setup script logged the history
database password in plain text to a world-readable file. An attacker with
a local user account on the Red Hat Enterprise Virtualization Manager
server could use this flaw to access, read, and modify the reports
database. (CVE-2014-0202)

Note: Applying the update provided by this advisory does not modify any
existing log files. It is recommended that you search your existing log
files and remove any occurrences of plain text passwords manually.

This issue was discovered by Red Hat.

This update also fixes the following bugs:

• Previously, the read-only user and custom users for the data warehouse

database would lose access to views in the database when the database was
upgraded. This was caused by the views being regenerated when the database
was upgraded and the permissions for those views not being applied to the
newly generated views. Now, user permissions are retained when the database
is upgraded. (BZ#1078129)

• Previously, the ovirt-engine-dwh-setup command would fail under certain

conditions if the pg_hba.conf file had been manually edited prior to
running that command. This was caused by the setup process checking the
exact number of spaces in between values on the line corresponding to
'local'. Now, the logic for checking the values in that line has been
revised so that the setup process can correctly read all values regardless
of the number of spaces. (BZ#1084760)

All rhevm-dwh users are advised to upgrade to this updated package, which
corrects these issues.
