Some vulnerabilities have been reported in FreeType, which can be exploited to cause a DoS (Denial of Service) or potentially compromise an application using the library.
1) An error exists in the "ft_var_readpackedpoints()" function in src/truetype/ttgxvar.c when processing TrueType GX fonts and can be exploited to cause a heap-based buffer overflow via a specially crafted font.
2) An error within the "Ins_SHZ()" function in src/truetype/ttinterp.c when handling the "SHZ" bytecode instruction can be exploited to cause a crash and potentially execute arbitrary code via a specially crafted font.
The vulnerabilities are reported in version 2.4.3. Other versions may also be affected.
