in brief Apple today has announced a new security update -- its fifth for the year -- with patches for 17 OS X vulnerabilities.
The update included fixes for users of Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.9, and Mac OS X Server v10.4.9.
The most serious of these vulnerabilities is for CoreGraphics in which an attacker could entice a user to open a specially crafted PDF file, resulting in an application crash and an overflow allowing the execution of malicious code.
Other serious patches include those for Bind, Fetchmail, and GNU Screen. The update is available from within Mac OS X via the Software Update pane in System Preferences, or from Apple's Software Downloads.












Sounds like mac os is going down the same path as windows.....
