-Description: missing boundary checks in layout engine
- It was discovered that ICU Layout Engine was missing multiple boundary checks.
- These could lead to buffer overflows and memory corruption.  A specially
- crafted file could cause an application using ICU to parse untrusted font
- files to crash and, possibly, execute arbitrary code.
