Log Message:
* Tue Oct 05 2010 Kevin Kofler <Kevin at tigcc.ticalc.org> 2.3.11-2
- Update the description to reflect that the bytecode interpreter is no longer
patented (but still disabled in the stock Fedora freetype).
- Add freetype-2.3.11-CVE-2010-2805.patch
(Fix comparison.)
- Add freetype-2.3.11-CVE-2010-2806.patch
(Protect against negative string_size. Fix comparison.)
- Add freetype-2.3.11-CVE-2010-2808.patch
(Check the total length of collected POST segments.)
- Add freetype-2.3.11-CVE-2010-3311.patch
(Don't seek behind end of stream.)
- Resolves: rh#638522
- Add freetype-2.3.11-CVE-2010-1797.patch
(Check stack after execution of operations too.
Skip the evaluations of the values in decoder, if
cff_decoder_parse_charstrings() returns any error.)
- Resolves: rh#621627
- Add freetype-2.3.11-CVE-2010-2498.patch
(Assure that `end_point' is not larger than `glyph->num_points')
- Add freetype-2.3.11-CVE-2010-2499.patch
(Check the buffer size during gathering PFB fragments)
- Add freetype-2.3.11-CVE-2010-2500.patch
(Use smaller threshold values for `width' and `height')
- Add freetype-2.3.11-CVE-2010-2519.patch
(Check `rlen' the length of fragment declared in the POST fragment header)
- Add freetype-2.3.11-CVE-2010-2520.patch
(Fix bounds check)
- Add freetype-2.3.11-CVE-2010-2527.patch
(Use precision for `%s' where appropriate to avoid buffer overflows)
- Add freetype-2.3.11-CVE-2010-2541.patch
(Avoid overflow when dealing with names of axes)
- Resolves: rh#613299
