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.

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.

Multiple vulnerabilities have been reported in Apple Safari, which can be exploited by malicious people to conduct cross-site scripting attacks, bypass certain security restrictions, and compromise a user's system.

1) Some vulnerabilities are caused due to a bundled vulnerable version of WebKit.

This is related to:
SA48321
SA48454 (#3)
SA48512 (#7)

2) An error related to stage tracking when handling forms can be exploited to populate forms on other websites.

The vulnerabilities are reported in versions prior to 5.1.7.

Update to version 5.1.7.
