Safari/Mail command execution - patched

Mail

CVE-ID: CVE-2006-0395

Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5

Impact: Download Validation fails to warn about unsafe file types

Description: In Mac OS X v10.4 Tiger, when an email attachment is double-clicked in Mail, Download Validation is used to warn the user if the file type is not "safe". Certain techniques can be used to disguise the file's type so that Download Validation is bypassed. This update addresses the issue by presenting Download Validation with the entire file, providing more information for Download Validation to detect unknown or unsafe file types in attachments.

Safari, LaunchServices

CVE-ID: CVE-2006-0394

Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X v10.4.5, Mac OS X Server v10.4.5

Impact: Viewing a malicious web site may result in arbitrary code execution

Description: It is possible to construct a file which appears to be a safe file type, such as an image or movie, but is actually an application. When the "Open `safe' files after downloading" option is enabled in Safari's General preferences, visiting a malicious web site may result in the automatic download and execution of such a file. A proof-of-concept has been detected on public web sites that demonstrates the automatic execution of shell scripts. This update addresses the issue by performing additional download validation so that the user is warned (in Mac OS X v10.4.5) or the download is not automatically opened (in Mac OS X v10.3.9).

There were a bunch of other updates as well, but these two made me happy.
