DESCRIPTION:
A vulnerability has been reported in FreeType, which can be exploited
to cause a DoS (Denial of Service) or potentially compromise an
application using the library.

The vulnerability is caused due to an error in the
"ft_var_readpackedpoints()" function in src/truetype/ttgxvar.c when
processing TrueType GX fonts. This can be exploited to cause a
heap-based buffer overflow via a specially crafted font.

The vulnerability is reported in version 2.4.3. Other versions may
also be affected.

SOLUTION:
Fixed in the Git repository.

PROVIDED AND/OR DISCOVERED BY:
Anonymous person via a FreeType bug report.
