<background>
<p>Pixman is a pixel manipulation library.</p>
</background>
<description>
<p>The trapezoid handling code in Pixman contains an integer underflow
vulnerability.
</p>
</description>
<impact type="normal">
<p>A context-dependent attacker could entice a user to open a specially
crafted file using an application linked against Pixman, possibly
resulting in 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 Pixman users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=x11-libs/pixman-0.32.4"
</code>
<p>Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
