877627: CVE-2012-4208 Mozilla: XrayWrappers exposes chrome-only properties when not in chrome compartment (MFSA 2012-99)

The MITRE CVE dictionary describes this issue as:

The XrayWrapper implementation in Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 does not consider the compartment during property filtering, which allows remote attackers to bypass intended chrome-only restrictions on reading DOM object properties via a crafted web site.
