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.

This covers various vulnerabilities where it is possible for malicious users or people to impersonate other users or systems.

Debian has issued an update for icedove. This fixes multiple vulnerabilities, which can be exploited by malicious people to conduct cross-site scripting and spoofing attacks and compromise a user's system.
