[OSSA 2014-036] Missing fix for ssh_execute (Exceptions thrown may contain passwords) (CVE-2014-7230, CVE-2014-7231)

Here is the updated impact description.

Title: Potential leak of passwords into log files
Reporter: Amrith Kumar (Tesora)
Products: Cinder and Nova (versions up to 2014.1.3)
                    Trove (versions up to 2014.1.2)

Description:
Amrith Kumar from Tesora reported two vulnerabilities in the processutils.execute() and strutils.mask_password() functions available from oslo-incubator that are copied into each project's code. An attacker with read access to the services' logs may obtain passwords used as a parameter of a command that have failed or when the mask_password did not mask passwords properly.

I have a couple minor English grammar corrections to suggest:

"... An attacker with read access to the services' logs may obtain passwords used as a parameter of a command that has failed or when mask_password did not mask passwords properly."

Aside from that, the impact description looks fine. The products header is conflated with our usual versions header, but as this is for different versions of two projects that is probably unavoidable.

    Mask passwords in exceptions and error messages

    When a ProcessExecutionError is thrown by processutils.ssh_execute(),
    the exception may contain information such as password. Upstream
    applications that just log the message (as several appear to do)
    could inadvertently expose these passwords to a user with read access to
    the log files. It is therefore considered prudent to invoke
    strutils.mask_password() on the command, stdout and stderr in the
    exception. A test case has been added (to oslo-incubator) in order to
    ensure that all three are properly masked.

    An earlier commit (853d8f9897f8563851441108a9be26b10908c076) failed

    commit a8a5d44c8aca218f00649232c2b8a46aee59b77e add pci_request_id
    as one item for the request_network tuple. But the icehouse code

    Fix broken cert revocation

    Cert revocation was broken by
    32b0adb591f80ad2c5c19519b4ffc2b55dbea672. os.chdir() never returns
    anything, so this method would always raise an exception. The proper
    way to handle an error from os.chdir() is to catch OSError.

    There were existing tests for this code, but they conveniently mocked
    os.chdir() to return values that are never actually returned. The
    tests were fixed to match the real behavior.

    Update all of the rpc client API classes to include a version alias

    ensure all services only send messages that both Juno and Kilo will
    understand.

    Fix LVM iSCSI driver tgtadm CHAP authentication

    Currently CHAP Authentication in LVM iSCSI driver with tgtadm does not work.
    This is because the tgtadm helper creates the target configuration file
    with an 'IncomingUser' entry, which is ignored by tgtd.
    This patch fixes it to 'incominguser'.

    Export cinder volumes only if the status is 'in-use'

    Currently, cinder volumes are exported both 'in-use' and 'available'
    after restarting cinder-volume service.
    This behavior was introduced following commit.

    If the volumes are attached to nova instances, they should be exported
    via tgtd after restarting cinder-volume.
    But the volumes which are not attached to instances must not be exported
    because everyone can connect these volumes.

    This patch changes volume export behavior that exports a volume only if
    the volume status is 'in-use'.
