Red Hat Enterprise Linux 5: RHSA-2013:1121-01 Low: Sos Security Update

Calendar Grey July 30, 2013
Dist Redhat Esm H88
A crucial patch for Red Hat Enterprise Linux 5 addressing a minor security flaw in the sos utility package.
An updated sos package that fixes one security issue is now available for Red Hat Enterprise Linux 5

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258

Summary

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.
The utility also collects yum repository information from "/etc/yum.repos.d" which in uncommon configurations may contain passwords. Any http_proxy password specified in these files will now be automatically removed. Passwords embedded within URLs in these files should be manually removed or the files excluded from the archive.
All users of sos are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
