Issue ID: 127929
Issue Type: DEFECT
Summary: Possible crash in Freetype code
Product: General
Version: 4.2.0-dev
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: Normal
Priority: P5 (lowest)
Component: code

Check the return value of the FT_Get_Glyph() function
Method FreetypeServerFont::InitGlyphData() calls function FT_Get_Glyph() but
does not check its return value.
On my system, the function fails when selecting the ``slide master'' in
Impress, and the program crashes because the method continues with invalid
data.
The attached patch repeats the same check as the previous call to
FT_Load_Glyph().
Please note I have no idea what a glyph is, what those FT_ functions do, and
why they fail. But the attached patch solves the crashes on my systems (tested
on Linux) and looks logical IMHO.
I suppose the same problem is present in version 4.1.5 (Linux and FreeBSD),
because it also crashes when selecting the slide master view.
Please let me know if you need any more information.
