Multiple vulnerabilities were discovered and corrected in freetype2 :

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 (CVE-2010-3814).

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 (CVE-2010-3855).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:
http://store.mandriva.com/product_info.php?cPath=149&products_id=4 90

The updated packages have been patched to correct these issues.
