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 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.
Debian has issued an update for typo3-src. This fixes some vulnerabilities, which can be exploited by malicious users to conduct script insertion attacks, disclose sensitive information, and compromise a vulnerable system and by malicious people to conduct cross-site scripting attacks.
