security fix in X11 (libxfont - xfree86)



Dear Security team,

a security patch has been applied to libxfont in unstable (libxfont
1:1.2.0-2). The bug relates to broken pcf font files and is referenced
in CVE-2006-3467.

xfree86 in sarge is also affected, so the patch will want to be applied
there too I think. The patch is named 10_pcf_font.patch and found at
http://necrotic.deadbeast.net/svn/xorg-x11/tags/lib/libxfont/1:1.2.0-2/debian/patches/.

The equivalent location in xfree86 is in xc/lib/font/.

It may possibly be appropriate to consider applying
10_freetype_buffer_overflow.patch as well.
