LibXfont is the X.Org font library. TightVNC is a VNC client/server for
|
|
X displays.

<description>
|
|
<p>
|
|
The libXfont code is prone to several integer overflows, in functions
|
|
ProcXCMiscGetXIDList(), bdfReadCharacters() and FontFileInitTable().
|
|
TightVNC contains a local copy of this code and is also affected.
|
|

|
|
<impact type="high">
|
|
<p>
|
|
A local attacker could use a specially crafted BDF Font to gain root
|
|
privileges on the vulnerable host.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All libXfont users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=x11-libs/libXfont-1.2.7-r1"</code>
|
|
<p>
|
|
All TightVNC users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/tightvnc-1.2.9-r4"</code>
