Description Josh Bressers 2007-05-18 15:14:00 UTC
This is the tracking bug for FC5 and FC6, please see the blocks list

+++ This bug was initially created as a clone of Bug #240200 +++

Victor Stinner discovered an integer overflow bug in the way freetype processed
malformed TTF fonts:

The patch can be found here:

It appears that this flaw will result in a heap overflow condition:

    flag_limit = flag + n_points;
    while ( flag < flag_limit )
      *flag++ = c = FT_NEXT_BYTE( p );

Comment 1 Behdad Esfahbod 2007-05-29 20:38:23 UTC
Built freetype-2.2.1-17.fc6

Comment 2 Alexei Podtelezhnikov 2007-06-01 15:50:33 UTC
why not 2.3.4??? Do not retard Fedora!!!

Comment 3 Behdad Esfahbod 2007-06-01 19:24:01 UTC
No thanks.  Every single freetype release since 2.2 have had its own very, very,
noisy surprises.  I'm sick of it and not going to update FC6's version of freetype.
