Policy files allowed servers to open up their data selectively to client content from other domains, or generally to content from anywhere. Since the introduction of policy files, domain boundaries have been less of a barrier for authors of rich Internet applications. Like most new technologies, policy files werent perfect when they were first introduced. After four years, the Internet security community has found two undesirable situations described later in this article that can arise from the existence of policy files. The basic premise of policy files remains valid, and Flash developers can continue to rely on policy files just as they have since Flash 6. To address the new concerns, however, Adobe is specifying some stricter rules for the use of policy files. Additionally, there are a number of improvements that make policy files more useful and usable. We will try to explain the reasons for our changes clearly and simply.

Security Update compatibility. How websites need to respond. To conform to the stricter rules, websites that serve policy files will need to make some minor changes. These changes are mainly for the protection of those sites themselvesessentially a new set of security best practices concerning policy files. For most sites, we dont expect the changes to be difficultbut because of the large number of sites impacted, Adobe implemented the stricter requirements in Flash Player in three phases. In Phase 1, which began with Flash Player 9,0,1. Debug versions of Flash Player. In Phase 1. 5, which began with Flash Player 9,0,1. Phase 1 became errors in the specific case of socket operations. In Phase 2, which began with Flash Player 1. Focus T25 Utorrent For Windows. Phase 1 became errors and the transition to stricter rules was complete. We recommend that website administrators follow these steps Immediately Read the section on immediate strictness, then follow the workflow steps for diagnosing and fixing immediate issues. This step only applies to sites that serve Flash Player compatible content SWF files. This step accounts for the effects of Phase 1. Immediately Read the section on socket policy files, then follow the workflow steps for configuring socket policy files. This step applies primarily to sites that already provide policy files, but can also provide useful defensive measures to sites with no policy files or SWF files. This step accounts for the effects of Phase 1. As time permits Read the section on meta policies, then follow the workflow steps for choosing and configuring a meta policy. This step applies primarily to sites that already provide policy files, but can also provide useful defensive measures to sites with no policy files or SWF files. This step accounts for the effects of Phase 2. Two issues are addressed by the stricter policy file rules Policy file control. There is a possibility that a file on a server that does not appear to be a policy file may in fact be used as a policy file. For example, if a server permits uploads by users, but does not intend to open data for cross domain access, it is possible that a user could deliberately construct a policy file but disguise it as a different type of file, such as an ordinary text, XML, or HTML file, or even as a binary type, such as a PNG or JPEG image file. A user who successfully uploaded this disguised policy file could then write a SWF file that takes advantage of the disguised policy file to load data from outside the servers domain. Similarly, a site maintainer with limited privileges could add a policy file to the site against an administrators wishes, or even accidentally create a policy file they did not intend to. This issue is essentially one of controlling what policy files are permitted to exist on a server. Server administrators should be able both to set a server wide policy on policy files we call this a meta policy, and to easily search for all policy files on their server, allowing auditing of all cross domain permissions present on the server. The stricter policy file rules in Flash Player allow meta policy declarations by server administrators, and perform greater sanity checking on policy files to help ensure that they are properly formatted. DNS hardening. A class of cross site scripting attacks known as DNS rebinding can target Flash Player, as well as browsers, virtual machines, and other user agent programs. A DNS rebinding attack exploits a user agents same origin policy, in which content from a given Internet domain is permitted to load and communicate with other resources in its own domain without explicit permission. An attacker who controls their own domain, and runs their own DNS server, can dynamically reconfigure their DNS server so that a given domain name resolves first to an IP address under the attackers control which may be used to serve a malicious SWF file or other content, then later to a different IP address that the attacker does not control. If the user agent program does not detect the change in IP addresses, its same origin policy will permit the attackers content to access the second IP address without permission from the second host. Flash Player relies on browsers to provide HTTP networking, so any rebinding vulnerabilities that involve only HTTP must be solved in browsers. However, Flash Player also provides socket level networking via the Action. Script Socket and XMLSocket classes, and the strict policy file rules in Flash Player 9,0,1. DNS rebinding vulnerabilities as they pertain to sockets. Specifically, the strict rules always require permission from a socket policy file in order to make a socket connection, even when the socket server appears to be the same as a connecting SWF files domain of origin. In addition, beginning with version 9,0,1.
