  <title>gdb: Multiple vulnerabilities</title>
  <synopsis>
    Multiple vulnerabilities have been discovered in the GNU debugger,
    potentially allowing the execution of arbitrary code.

    <p>
    gdb is the GNU project's debugger, facilitating the analysis and
    debugging of applications. The BFD library provides a uniform method of
    accessing a variety of object file formats.
    </p>
  </background>
  <description>
    <p>
    Tavis Ormandy of the Gentoo Linux Security Audit Team discovered an
    integer overflow in the BFD library, resulting in a heap overflow. A
    review also showed that by default, gdb insecurely sources
    initialisation files from the working directory.
    </p>
  </description>
  <impact type="normal">
    <p>
    Successful exploitation would result in the execution of arbitrary code
    on loading a specially crafted object file or the execution of
    arbitrary commands.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All gdb users should upgrade to the latest stable version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sys-devel/gdb-6.3-r3"</code>
  </resolution>
