Firefox 22 has been officially released and, according to Mozilla’s security advisory, the latest version addresses a total of 14 vulnerabilities that could have been exploited by cybercriminals.

Four of the security holes – a privileged content access and execution via XBL, a memory corruption issue, execution of unmapped memory through “onreadystatechange” event, and some miscellaneous memory safety hazards – are catalogued as being critical.

The six high-severity flaws fixed in Firefox 22 can be leveraged to gather sensitive data from sites, or to inject data or code into those sites.

In addition, three moderate and one low-impact issues have also been addressed.

Users are advised to update their installations as soon as possible.
