<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>
