  <title>libwmf: Buffer overflow vulnerability</title>
  <synopsis>
    libwmf is vulnerable to an integer overflow potentially resulting in the
    execution of arbitrary code.

  <bug>139325</bug>
  <access>remote</access>
  <affected>
    <package name="media-libs/libwmf" auto="yes" arch="*">
      <unaffected range="ge">0.2.8.4</unaffected>
      <vulnerable range="lt">0.2.8.4</vulnerable>

  <background>
    <p>
    libwmf is a library for reading and converting vector images in
    Microsoft's native Windows Metafile Format (WMF).
    </p>
  </background>
  <description>
    <p>
    infamous41md discovered that libwmf fails to do proper bounds checking
    on the MaxRecordSize variable in the WMF file header. This could lead
    to an head-based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>
    By enticing a user to open a specially crafted WMF file, a remote
    attacker could cause a heap-based buffer overflow and execute arbitrary
    code with the permissions of the user running the application that uses
    libwmf.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround for this issue.
    </p>
  </workaround>
  <resolution>
    <p>
    All libwmf users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-libs/libwmf-0.2.8.4&quot;</code>
  </resolution>
