Red Hat Network (RHN) Configuration Client (rhncfg-client) in rhncfg before 5.10.27-8 uses weak permissions (world-readable) for /var/log/rhncfg-actions, which allows local users to obtain sensitive information about the rhncfg-client actions by reading the file.

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:1369 advisory.

    Red Hat Network Tools provide programs and libraries that allow your system     to use provisioning, monitoring, and configuration management capabilities     provided by Red Hat Network and Red Hat Network Satellite.

    It was discovered that the Red Hat Network (RHN) Configuration Client     (rhncfg-client) tool set world-readable permissions on the     /var/log/rhncfg-actions file, used to store the output of different     rhncfg-client actions (such as diffing and verifying files). This could     possibly allow a local attacker to obtain sensitive information they would     otherwise not have access to. (CVE-2012-2679)

    Note: With this update, rhncfg-client cannot create diffs of files that     are not already world-readable, and /var/log/rhncfg-actions can only be     read and written to by the root user.

    This issue was discovered by Paul Wouters of Red Hat.

    This update also fixes the following bugs:

    * When the user attempted to use the rhncfg-client get command to     download a backup of deployed configuration files and these configuration     files contained a broken symbolic link, the command failed with an error.
    This update ensures that rhncfg-client get no longer fails in this     scenario. (BZ#836445)

    * The SYNOPSIS section of the rhn-actions-control(8) manual page has been     updated to include the --report command line option as expected.
    (BZ#820517)

    As well, this update adds the following enhancement:

    * The rhncfg-manager utility now supports a new command line option,
    --selinux-context. This option can be used to upload files and     directories without setting the Security-Enhanced Linux (SELinux) context.
    (BZ#770575)

    All users of Red Hat Network Tools are advised to upgrade to these updated     packages, which correct these issues and add this enhancement.
