Description Josh Bressers 2006-08-14 18:03:40 UTC 
+++ This bug was initially created as a clone of Bug #202469 +++

An integer overflow was discovered in the way freetype processes malformed PCF
files.  It seems that Xorg also contains the same PCF processing code as
freetype, there it too is vulnerable this issue.

We initally described this issue for freetype in bug 190593.

The upstream bug is here:
