Apple Computer has released one of its largest ever security updates to fix 44 flaws in its new Tiger operating system and older versions of its main OS.
Some of the flaws fixed by Apple are previously publicised vulnerabilities, which have so far have not been affected by any exploit code, while others are more serious.
The flaws include holes in AppKit, which is used to open rich text files (RTFs), and in the Safari Web browser.
The AppKit vulnerability allows a remote attacker to create a malicious file that causes a buffer overflow, and the opportunity to execute malicious code on a user’s machine.
Holes in Safari allow an attacker to bypass the browser’s security checks and execute code after the user clicks on a malicious rich text file.
Apple released a raft of security patches in March and June this year, which also included fixes for Safari.
