Description Richard Chan 2004-11-09 09:58:35 UTC
Description of problem:

fontconfig crashes on the font file MSungStd-Light-Acro.otf
when creating the fonts.cache-1 file. fc-cache will segfault
when processing a directroy with this file.
The existence of this file prevents X start-up on window
managers using fontconfig


Version-Release number of selected component (if applicable):
2.2.3-5

How reproducible:
Always


Steps to Reproduce:
1. Get the font file from Adobe Asian Font Packs
http://www.adobe.com/products/acrobat/acrrasianfontpack.html
by choosing
Adobe Acrobat 5.x
Chinese Traditional
UNIX
You will get a chtfont.tar.gz file containing the MSung... file
2. The file is 8351624 bytes with md5sum 
42aa2141a7406922f301108a1328bd0f
3. Create a directory for the file and put the directory in
/etc/fonts/local.conf
4. Run fc-cache -v -f
  
Actual results:
fc-cache will segfault on the directory containing this
font file


Expected results:
fc-cache will correctly create the cache file


Additional info:
This works on FC2 - could be problem in the fontconfig library.

Comment 1 Richard Chan 2004-11-09 10:05:05 UTC
Unfortunately the font file is too large to attach here - my apologies
for making you go through hoops to access the font but it is 
directly  available at
ftp://ftp.adobe.com/pub/adobe/acrobatreader/unix/5.x/chtfont.tar.gz

Comment 2 Richard Chan 2004-11-09 10:11:25 UTC
Tracked this down to freetype - I replaced libfreetype.so.6
with the library from FC2 and it works.

Comment 3 Richard Chan 2004-11-10 03:22:56 UTC
Faulty version of freetype is 2.1.9-1 as shipped
with Fedora Core 3. FC2's freetype-2.1.7-4 is ok.
Other large otfs from Adobe (e.g. Chinese Simplified, Japanese)

ftp://ftp.adobe.com/pub/adobe/acrobatreader/unix/5.x/chsfont.tar.gz
STSongStd-Light-Acro.otf 
ftp://ftp.adobe.com/pub/adobe/acrobatreader/unix/5.x/jpnfont.tar.gz
KozMinPro-Regular-Acro.otf

don't trigger this problem in FC3.

Comment 4 Matthias Clasen 2005-10-21 20:15:07 UTC
Do you know if the problem still occurs with freetype 2.1.10 ?

Comment 5 Richard Chan 2005-10-22 01:22:02 UTC

Fixed using 2.1.10 from rawhide (problem still occurs with 2.1.9 in Core 4); can
generate cache file now.

The correct fontconfig cache file

This cache file is correctly generated by freetype 2.10 in rawhide 2005-10-09.
fc-cache crashes on this font file all the way from FC3 to FC4 with 2.1.9.

Comment 7 Richard Chan 2005-10-22 01:25:40 UTC
Oops - that should be rawhide 2005-10-22.

Comment 8 Matthew Miller 2006-07-10 20:36:28 UTC
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.

Thank you!


Comment 9 John Thacker 2006-10-30 21:41:18 UTC
Closing since it works in FC5 and forward, and FC3 and FC4 are maintained by
Fedora Legacy for security updates only.
