Synopsis

Low: sos security, bug fix, and enhancement update

Type/Severity

Security Advisory: Low

Topic

An updated sos package that fixes one security issue, several bugs, and
adds various enhancements is 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 sos package contains a set of tools that gather information from system
hardware, logs and configuration files. The information can then be used
for diagnostic purposes and debugging.

The sosreport utility collected the Kickstart configuration file
("/root/anaconda-ks.cfg"), but did not remove the root user's password from
it before adding the file to the resulting archive of debugging
information. An attacker able to access the archive could possibly use this
flaw to obtain the root user's password. "/root/anaconda-ks.cfg" usually
only contains a hash of the password, not the plain text password.
(CVE-2012-2664)

Note: This issue affected all installations, not only systems installed via
Kickstart. A "/root/anaconda-ks.cfg" file is created by all installation
types.

This updated sos package also includes numerous bug fixes and enhancements.
Space precludes documenting all of these changes in this advisory. Users
are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for
information on the most significant of these changes.

All users of sos are advised to upgrade to this updated package, which
contains backported patches to correct these issues and add these
enhancements.
