  <title>libuv: Privilege escalation</title>
  <synopsis>A vulnerability in libuv could lead to privilege escalation.</synopsis>
  <product type="ebuild"/>

  <bug>540826</bug>
  <access>local, remote</access>
  <affected>
    <package name="dev-libs/libuv" auto="yes" arch="*">
      <unaffected range="ge">1.4.2</unaffected>
      <vulnerable range="lt">1.4.2</vulnerable>
    </package>
  </affected>
  <background>
    <p>libuv is a multi-platform support library with a focus on asynchronous
      I/O.
    </p>
  </background>
  <description>
    <p>It was discovered that libuv does not call setgroups before calling
      setuid/setgid.  If this is not called, then even though the uid has been
      dropped, there may still be groups associated that permit superuser
      privileges.
    </p>
  </description>
  <impact type="normal">
    <p>Context-dependent attackers could escalate privileges via unspecified
      vectors.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libuv users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --verbose --oneshot "&gt;=dev-libs/libuv-1.4.2"
    </code>
