  <title>GIMPS: Root privilege escalation</title>
  <synopsis>Gentoo's GIMPS ebuilds are vulnerable to privilege escalation due
    to improper permissions. A local attacker could use it to gain root
    privileges.

    <p>GIMPS, the Great Internet Mersenne Prime Search, is a software capable
      of find Mersenne Primes, which are used in cryptography. GIMPS is also
      used for hardware testing.

  <description>
    <p>It was discovered that Gentoo’s default GIMPS installation suffered
      from a privilege escalation vulnerability in the init script. This script
      calls an unsafe “chown -R” command in checkconfig() function.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker who does not belong to the root group, but has the
      ability to modify the /var/lib/gimps directory can escalate privileges to
      the root group.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GIMPS users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sci-mathematics/gimps-28.10-r1"
    </code>
