Mozilla Foundation Security Advisories[end quoted excerpt]
Impact key
Critical Vulnerability can be used to run attacker code and install software,
requiring no user interaction beyond normal browsing.
High Vulnerability can be used to gather sensitive data from sites in other
windows or inject data or code into those sites, requiring no more than normal
browsing actions.
Moderate Vulnerabilities that would otherwise be High or Critical except they
only work in uncommon non-default configurations or require the user to perform
complicated and/or unlikely steps.
Low Minor security vulnerabilities such as Denial of Service attacks, minor
data leaks, or spoofs. (Undetectable spoofs of SSL indicia would have "High"
impact because those are generally used to steal sensitive data intended for
other sites.)
