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.

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Mariusz Mlynski as the original reporter.
