TITLE:
Mozilla Firefox Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA34758
VERIFY ADVISORY:
http://secunia.com/advisories/34758/
DESCRIPTION:
Some vulnerabilities, security issues, and a weakness have been
reported in Mozilla Firefox, which can be exploited by malicious
people to disclose potentially sensitive information, bypass
certain
security restrictions, conduct cross-site scripting and
cross-site
request forgery attacks, and potentially compromise a user's
system.
1) Multiple errors in the browser engine can be exploited to
corrupt
memory and potentially execute arbitrary code.
2) Multiple errors in the JavaScript engine can be exploited to
corrupt memory and potentially execute arbitrary code.
3) An error exists when the "jar:" scheme is used to wrap a URI,
which serves content with "Content-Disposition: attachment". This
can
be exploited to e.g. conduct cross-site scripting attacks on
sites
that allow users to upload arbitrary content, which is served as
"application/java-archive" or "application/x-jar", and that rely
on
the HTTP header "Content-Disposition: attachment" to prevent
potentially untrusted content.
4) An error when loading a Adobe Flash file via the
"view-source:"
scheme can be exploited to conduct cross-site request forgery
attacks
or read and write Local Shared Objects on a user's system e.g.
for
tracking purposes.
5) An error in the processing of XBL bindings can be exploited to
conduct script insertion attacks on sites that allow user to
embed
third-party stylesheets.
6) Errors in "XMLHttpRequest" and "XPCNativeWrapper.toString" can
be
exploited to bypass the same-origin policy and potentially
execute
code with chrome privileges.
7) A weakness in the handling of "SearchForm" URIs can be
exploited
to execute arbitrary script code in the context of an arbitrary
site
when a user performs an empty search in a specially crafted
plugin.
8) An error in the handling of POST data may result in unintended
information disclosure. When an inner frame of a web page is
saved as
file POST data of the outer page is sent to the URL of the inner
frame.
9) An error in the processing of the "Refresh" header can
potentially
be exploited to conduct cross-site scripting attacks.
The vulnerabilities are reported in versions prior to 3.0.9.
SOLUTION:
Update to version 3.0.9.
