The Gecko Media Plugin sandbox allows access to local files that match specific regular expressions. On OS OX, this matching allows access to some data in subdirectories of /private/var that could expose personal or temporary data. This has been updated to not allow access to /private/var and its subdirectories. Note: this issue only affects OS X. Other operating systems are not affected.
