<background>
<p>
libXpm is a pixmap manipulation library for the X Window System,
included in both X.Org and XFree86.
</p>
</background>
<description>
<p>
Several issues were discovered in libXpm, including integer
overflows, out-of-bounds memory accesses, insecure path traversal and
an endless loop.
</p>
</description>
<impact type="normal">
<p>
An attacker could craft a malicious pixmap file and entice a user
to use it with an application linked against libXpm. This could lead to
Denial of Service or arbitrary code execution.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All X.Org users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=x11-base/xorg-x11-6.7.0-r3&quot;</code>
<p>
All XFree86 users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=x11-base/xfree-x11-4.3.0-r8&quot;</code>
