Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious, local users to potentially disclose sensitive information, and by malicious people to conduct cross-site scripting attacks, bypass certain security restrictions, disclose sensitive information, or potentially to compromise a user's system.
1) Multiple errors in the layout engine can be exploited to cause memory corruptions and potentially execute arbitrary code.
4) An error when restoring a closed tab can be exploited to modify an input control's text value, which allows e.g. to disclose the content of a local file when a user re-opens a tab.
5) An error in the processing of shortcut files can be exploited to execute arbitrary script code with chrome privileges e.g. via an HTML file that loads a privileged chrome document via a .desktop shortcut file.
7) A security issue is caused due to Firefox ignoring certain HTTP directives to not cache web pages ("Cache-Control: no-store" and "Cache-Control: no-cache" for HTTPS pages), which can be exploited to disclose potentially sensitive information via cached pages.
Solution: Update to version 3.0.6.
