Description Huzaifa S. Sidhpurwala 2010-10-21 08:02:57 UTC 
A heap based buffer overflow was found in the "ft_var_readpackedpoints()" function in src/truetype/ttgxvar.c when processing TrueType GX fonts.

If a user opened a specially crafted TrueType GX font file, with an application complied with freetype library, it could cause denial of service (application crash) or potentially execute arbitrary code with the privileges of the user 
running that application.
