    <p>
    E2fsprogs provides utilities for use with the ext2 and ext3 file
    systems including the libext2fs library that allows user-level programs
    to manipulate an ext2 or ext3 file system.
    </p>

  <description>
    <p>
    Rafal Wojtczuk (McAfee AVERT Research) discovered multiple integer
    overflows in libext2fs, that are triggered when processing information
    from within the file system, resulting in heap-based buffer overflows.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could entice a user to process a specially-crafted ext2 or
    ext3 file system image (with tools linking against libext2fs, e.g.
    fsck, forensic tools or Xen's pygrub), possibly resulting in the
    execution of arbitrary code with the privileges of the user running the
    application.
    </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-1.40.3"</code>
