These vulnerabilities have been corrected in libpng which is used by the CoreGraphics and AppKit frameworks in Mac OS X. After installing this update, applications that use the PNG image format via these frameworks will be protected against these flaws. Note: The libpng security fixes are also available separately for Mac OS X 10.3.4 and Mac OS X 10.2.8 via Security Update 2004-08-09. Component: Safari CVE ID: CAN-2004-0743 Impact: In a special situation, navigation using the forward/backward buttons can re-send form data to a GET url. Description: This is for a situation where a web form is sent to a server using a POST method which issues an HTTP redirect to a GET method url. Using the forward/backward buttons will cause Safari to re-POST the form data to the GET url. Safari has been modified so that in this situation forward/backward navigation will result in only a GET method. Component: TCP/IP Networking CVE ID: CAN-2004-0744 Impact: Maliciously crafted IP fragments can use too many system resources preventing normal network operation. Description: The "Rose Attack" describes a specially constructed sequence of IP fragments designed to consume system resources.
