Risk: High
The flaws in a variety of Mozilla products range in criticality - the most serious would enable arbitrary code execution or theft of sensitive information from PCs using Mozilla products. If some flaws were to be exploited, it would also be relatively easy to construct phishing attacks. Other consequences of vulnerabilities being exploited could be security bypasses, as well as cross site scripting attacks and Denial of Service attacks being enabled
All Mozilla users should upgrade to the next available version urgently at www.mozilla.org.
