Description Huzaifa S. Sidhpurwala 2016-06-06 00:20:18 EDT

Mozilla developer John Schoenick reported that CSS pseudo-classes can be used by web content to leak information on plugins that are installed but disabled. This can be used for information disclosure through a fingerprinting attack that lists all of the plugins installed by a user on a system, even when they are disabled.
