  <title>Pulseaudio: Privilege escalation</title>
  <synopsis>
    A vulnerability in pulseaudio may allow a local user to execute actions
    with escalated privileges.
  </synopsis>

  <affected>
    <package name="media-sound/pulseaudio" auto="yes" arch="*">
      <unaffected range="ge">0.9.9</unaffected>

  <background>
    <p>
    Pulseaudio is a networked sound server with an advanced plugin system.
    </p>

  <description>
    <p>
    Marcus Meissner from SUSE reported that the pa_drop_root() function
    does not properly check the return value of the system calls setuid(),
    seteuid(), setresuid() and setreuid() when dropping its privileges.
    </p>
  </description>
  <impact type="high">
    <p>
    A local attacker could cause a resource exhaustion to make the system
    calls fail, which would cause Pulseaudio to run as root. The attacker
    could then perform actions with root privileges.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Pulseaudio users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-sound/pulseaudio-0.9.9"</code>
  </resolution>
