The version CM10.1.1 of the popular Android 4.2.2 custom ROM is aimed at fixing some security vulnerabilities and issues.

Here is a list of issues that this release fixes:

What’s New in CM 10.1.1

This release patches security vulnerabilities and does NOT include any new features. Following vulnerabilities have been patched:
