Description Sam Fowler 2018-06-28 03:29:37 UTC 
SPICE has a vulnerability caused by a missing check in python_modules/demarshal.py:write_validate_array_item() which results in generated demarshalling code being vulnerable to multiple buffer overflows. An attacker could exploit this to cause a denial of service.
