Synopsis:	Critical: firefox security update
Issue date:	2009-06-11
CVE Names:	CVE-2009-1392 CVE-2009-1832 CVE-2009-1833
 CVE-2009-1834 CVE-2009-1835 CVE-2009-1836
 CVE-2009-1837 CVE-2009-1838 CVE-2009-1839
 CVE-2009-1840 CVE-2009-1841

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code as the user running Firefox.
(CVE-2009-1392, CVE-2009-1832, CVE-2009-1833, CVE-2009-1837, CVE-2009-1838,
CVE-2009-1841)

Multiple flaws were found in the processing of malformed, local file
content. If a user loaded malicious, local content via the file:// URL, it
was possible for that content to access other local data. (CVE-2009-1835,
CVE-2009-1839)

A script, privilege elevation flaw was found in the way Firefox loaded
XML User Interface Language (XUL) scripts. Firefox and certain add-ons
could load malicious content when certain policy checks did not happen.
(CVE-2009-1840)

A flaw was found in the way Firefox displayed certain Unicode characters
in International Domain Names (IDN). If an IDN contained invalid
characters, they may have been displayed as spaces, making it appear to
the user that they were visiting a trusted site. (CVE-2009-1834)

A flaw was found in the way Firefox handled error responses returned
from proxy servers. If an attacker is able to conduct a
man-in-the-middle attack against a Firefox instance that is using a
proxy server, they may be able to steal sensitive information from the
site the user is visiting. (CVE-2009-1836)

After installing the update, Firefox must be restarted for the changes
to take effect.
