Apple published a hefty software update last week to fix more than four dozen flaws in components of its Mac OS X operating system.

A large variety of code and libraries are affected by the patch, including the CoreText library, the Mac OS X printing component, two flaws in the Remote Apple Events code, the Safari Web browser, and the filesystem events framework. A number of open-source software packages used by Mac OS X were also were fixed by Apple's patch, including 14 flaws in the X11 windowing system code, 10 vulnerabilities in the interpreter for the python programming language, and two issues in the ClamAV antivirus program.

The update also fixes two issues in Apple's CFNetwork component that are not security related, the company stated in its advisory.

Apple released a separate update that fixed four security issues in the version of Java shipped with Mac OS X and a third update to fix a single security problem in its Safari browser for the Microsoft Windows platform.

The updates can be applied using Apple's update utility available under the Apple menu on Mac OS X and using the Apple Software Update utility on Windows systems.
