  <synopsis>A vulnerability was discovered in Gentoo's ebuild for BURP which
    could lead to root privilege escalation.

    <package name="app-backup/burp" auto="yes" arch="*">

  <description>
    <p>It was discovered that Gentoo’s BURP ebuild does not properly set
      permissions or place the pid file in a safe directory. Additionally, the
      first set of patches did not completely address this.  As such, a
      revision has been made available that addresses all concerns of the
      initial report.
    </p>
  </description>
  <impact type="normal">
    <p>A local attacker could escalate privileges.</p>
  </impact>
  <workaround>
    <p>Users should ensure the proper permissions are set as discussed in the
      referenced bugs.
    </p>
  </workaround>
  <resolution>
    <p>All BURP users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-backup/burp-2.1.32-r1"
    </code>
