Description Huzaifa S. Sidhpurwala 2012-11-17 07:02:49 EST
Security researcher Mariusz Mlynski reported that when a maliciously crafted stylesheet is inspected in the Style Inspector, HTML and CSS can run in a chrome privileged context without being properly sanitized first. This can lead to arbitrary code execution.
