Where	From remote "From remote" describes other vulnerabilities where the attack vector doesn't require access to the system or a local network. This category covers services that are acceptable to expose to the Internet (e.g. HTTP, HTTPS, SMTP). It also covers client applications used on the Internet and certain vulnerabilities where it is reasonable to assume that a security conscious user can be tricked into performing certain actions.
Impact	DoS (Denial of Service) This includes vulnerabilities ranging from excessive resource consumption (e.g. causing a system to use a lot of memory) to crashing an application or an entire system. System access This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user. Cross-Site Scripting Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system. Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery". Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks. Exposure of sensitive information Vulnerabilities where documents or credentials are leaked or can be revealed either locally or from remote. Manipulation of data This includes vulnerabilities where a user or a remote attacker can manipulate local data on a system, but not necessarily be able to gain escalated privileges or system access. The most frequent type of vulnerabilities with this impact are SQL-injection vulnerabilities, where a malicious user or person can manipulate SQL queries. Privilege escalation This covers vulnerabilities where a user is able to conduct certain tasks with the privileges of other users or administrative users. This typically includes cases where a local user on a client or server system can gain access to the administrator or root account thus taking full control of the system. Security Bypass This covers vulnerabilities or security issues where malicious users or people can bypass certain security mechanisms of the application. The actual impact varies significantly depending on the design and purpose of the affected application. Unknown Covers various weaknesses, security issues, and vulnerabilities not covered by the other impact types, or where the impact isn't known due to insufficient information from vendors and researchers.
Description	Some vulnerabilities have been reported in Adobe Flash Player, where one vulnerability has an unknown impact and others can be exploited by malicious, local users to gain escalated privileges and by malicious people to bypass certain security restrictions, conduct cross-site scripting and HTTP request splitting attacks, disclose sensitive information, cause a Denial of Service (DoS), or to potentially compromise a user's system. 1) An error when parsing specially crafted regular expressions can be exploited to cause a heap-based buffer overflow. For more information see vulnerability #7 in: SA27543 2) An error exists in the processing of SWF embedded JPG images. This can be exploited to corrupt the heap via specially crafted X and Y densities specified in the JPG header. 3) An error exists when pinning a hostname to an IP address. This can be exploited to conduct DNS rebinding attacks via allow-access-from elements in cross-domain-policy XML documents. 4) An error exists in the enforcing of cross-domain policy files. This can be exploited to bypass certain security restrictions on web servers hosting cross-domain policy files. 5) Input passed to unspecified parameters when handling the "asfunction:" protocol is not properly sanitised before being returned to the user. This can be exploited to inject arbitrary HTML and script code in a user's browser session in context of an affected site. The vulnerability does not affect Flash Player 7. 6) An error exists within the processing of the "navigateToURL" function. This can be exploited to execute arbitrary script code in the security context of another domain via a specially crafted "javascript:" URI. The vulnerability only affects the Flash Player ActiveX Control for Internet Explorer. 7) An unspecified error can be exploited to modify HTTP headers and conduct HTTP request splitting attacks. 8) An error within the implementation of the Socket or XMLSocket ActionScript classes can be exploited to determine if a port on a remote host is opened or closed. 9) An error within the setting of memory permissions in Adobe Flash Player for Linux can be exploited by malicious, local users to gain escalated privileges. 10) An unspecified error exists in Adobe Flash Player and Opera on Mac OS X. For more information see vulnerability #3 in: SA27277 The vulnerabilities are reported in versions prior to 9.0.115.0.
Solution	Update to version 9.0.115.0. Flash Player 9.0.48.0: http://www.stage.adobe.com/go/getflash Flash Player 9.0.48.0 and earlier - network distribution: http://www.stage.adobe.com/licensing/distribution Flash CS3 Professional: http://www.adobe.com/support/flash/downloads.html Flex 2.0: http://www.stage.adobe.com/support/flashplayer/downloads.html#fp9 The vulnerabilities are also fixed in Flash Player 7.0.73.0, which is available for operating systems that are not supported by Flash Player 9. NOTE: This is reportedly the final security bulletin that Adobe will supply for users of Adobe Flash Player 7 (formerly Macromedia Flash Player 7).
