Apple Computer released an update to its Mac OS X operating system on Tuesday to fix 15 security issues in the software.

Many of the problems are flaws in the operating system’s underlying open-source software, including a critical flaw in the Kerberos authentication system–software that can act as a gatekeeper for computer networks. The patch is available for Mac OS X 10.3.5 and Mac OS X 10.3.4, and also fixes issues in Mac OS X 10.2, known as “Jaguar.” “All security enhancements…are also available for Jaguar, if the issue could occur on Jaguar systems,” a security advisory from the company said.
