Apple Computer Inc. on Friday updated Mac OS X 10.4 to patch 15 vulnerabilities in the operating system and bundled software that can let attackers run malicious code, crash the computer, or gain unauthorized access to the machine.

According to the alert that Apple released alongside the update, more than half of the fixed flaws can lead to “arbitrary code execution.” In plain English, that means a hacker could hijack the Mac and install his own software on the system. Four of the bugs are in Flash, the Adobe-sold animation player bundled with Mac
OS X.
