Apple has released a fresh security update to address several security flaws, which is recommended for all OS X users.

The update - Security Update 2004-09-30 - was originally intended for release last week, but its release was delayed, as parts of Cupertino and other nearby cities suffered a power blackout late last week, reports claim.

Security improvements cover: AFP Server, CUPS, NetInfoManager, postfix and QuickTime. The latter addresses a heap buffer overflow problem that could allow malicious users to execute code hidden in a BMP (Bitmap) file. This has been repaired.

Detailed information on the update is available from Apple.
