      file systems.

  <description>
    <p>A heap-based buffer overflow was discovered in openfs.c in the libext2fs
      library in e2fsprogs.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to use ext2fs library (for
      example, fsck) on a specially crafted Ext2/3/4 file system possibly
      resulting in the execution of arbitrary code with the privileges of the
      process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All e2fsprogs users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-fs/e2fsprogs-1.42.12"
    </code>
