QuickTime for Java on Mac OS X 10.4 through 10.4.8, when used with Quartz Composer, allows remote attackers to obtain sensitive information (screen images) via a Java applet that accesses images that are being rendered by other embedded QuickTime objects.
Safari on Apple Mac OS X 10.4.6, when "Open safe' files after downloading" is enabled, will automatically expand archives, which could allow remote attackers to overwrite arbitrary files via an archive that contains a symlink.
WebKit on Apple Mac OS X 10.4 through 10.4.10 does not create temporary files securely when Safari is previewing a PDF file, which allows local users to read the contents of that file.
A cleanup script in crontabs in Apple Mac OS X 10.3.9 and 10.4.9 might delete filesystems that have been mounted in /tmp, which might allow local users to cause a denial of service, related to the find command.
