APPLE-SA-2008-07-11 Xcode tools 3.1

Xcode tools 3.1 is now available and addresses the following issues:

CoreImage Examples
CVE-ID:  CVE-2008-2304
Available for:  Mac OS X v10.5.x
Impact:  Opening a Fun House document may lead to an unexpected
application termination or arbitrary code execution
Description:  Xcode tools contain an example application called Core
Image Fun House that handles content with the ".funhouse" extension.
A buffer overflow may occur in this application when processing
".funhouse" files. Opening a maliciously-crafted ".funhouse" file may
lead to an unexpected application termination or arbitrary code
execution. This update addresses the issue through improved bounds
checking. Credit to Kevin Finisterre of Netragard for reporting this
issue.

WebObjects
CVE-ID:  CVE-2008-2318
Available for:  Mac OS X v10.5.x
Impact:  WebObjects session IDs may be disclosed to other web sites
Description:  WebObjects contains an API to generate URLs in HTML
documents via the WOHyperlink dynamic element. When WOHyperlink is
used, it always appends a session ID to the generated URL, even for
absolute URLs. Using WOHyperlink to create URLs that point at other
web sites may result in the disclosure of the current user's session
ID to those sites. This update addresses the issue by appending
session IDs to absolute URLs only when explicitly requested.
