"Alban Crequy and Simon McVittie discovered several vulnerabilities in
the D-Bus message daemon.

  - CVE-2014-3635
    On 64-bit platforms, file descriptor passing could be
    abused by local users to cause heap corruption in
    dbus-daemon, leading to a crash, or potentially to
    arbitrary code execution.

  - CVE-2014-3636
    A denial-of-service vulnerability in dbus-daemon allowed
    local attackers to prevent new connections to
    dbus-daemon, or disconnect existing clients, by
    exhausting descriptor limits.

  - CVE-2014-3637
    Malicious local users could create D-Bus connections to
    dbus-daemon which could not be terminated by killing the
    participating processes, resulting in a
    denial-of-service vulnerability.

  - CVE-2014-3638
    dbus-daemon suffered from a denial-of-service
    vulnerability in the code which tracks which messages
    expect a reply, allowing local attackers to reduce the
    performance of dbus-daemon.

  - CVE-2014-3639
    dbus-daemon did not properly reject malicious
    connections from local users, resulting in a
    denial-of-service vulnerability."
