Description Huzaifa S. Sidhpurwala 2012-08-27 03:39:06 UTC
Security researcher Mariusz Mlynski reported that when a page opens a new tab, a subsequent window can then be opened that can be navigated to about:newtab, a chrome privileged page. Once about:newtab is loaded, the special context can potentially be used to escalate privilege, allowing for arbitrary code execution on the local system in a maliciously crafted attack.
