<impact type="normal">
|
|
<p>
|
|
A local attacker could possibly execute arbitrary code or crash the
|
|
Xserver by enticing a user to load a specially crafted PCF font file.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not use untrusted PCF Font files.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All libXfont users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=x11-libs/libXfont-1.2.0-r1"</code>
