Mozilla Multiple Vulnerabilities Description

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

1) An error, where blocked popups opened through the GUI incorrectly
runs with "chrome" privileges, can be exploited to execute arbitrary code via a
specially crafted "javascript:" URI.
Successful exploitation requires that the user opens a blocked popup.

2) An error, where the global scope of a window or tab in certain
situations is not properly cleaned before navigating to a new web site, can be
exploited to execute arbitrary script code in a user"s browser session in context of
the new site.

3) An error, where the URL of a "favicons" icon for a web site is not
verified before being changed via JavaScript, can be exploited to
execute arbitrary script code with escalated privileges via a specially crafted
"javascript:" URI.
Successful exploitation may allow execution of arbitrary code.

4) An error, where the action URL of a search plugin is not verified
before being used to perform a search, can be exploited to execute arbitrary
script code in a user"s browser session in context of the current web site,
but requires that the user is tricked into installing a search plugin with
a specially crafted "javascript:" URI.
Successful exploitation may allow execution of arbitrary code, if a
search is performed when the current web site runs with escalated privileges
(e.g."about:plugins" and "about:config").

5) Some input validation errors when handling parameters of invalid
types passed to certain "InstallTrigger" and "XPInstall" related
objects via JavaScript may be exploited to execute arbitrary code.

6) Some errors, where certain privileged UI code does not properly
validate DOM nodes from the content window, can be exploited to execute arbitrary
code. Successful exploitation may require some user interaction.
