SECUNIA ADVISORY ID:
SA32011

VERIFY ADVISORY:
http://secunia.com/advisories/32011/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Exposure of system information, Exposure of

SOFTWARE:
Mozilla Firefox 3.x
http://secunia.com/advisories/product/19089/

DESCRIPTION:
Some vulnerabilities have been reported in Mozilla Firefox, which can
be exploited by malicious people to bypass certain security
restrictions, to disclose sensitive information, or to potentially
compromise a user's system.

1) An error in the JavaScript move and resize functionality can be
exploited to trick the user into clicking an unintended button and
e.g. download a malicious file.

2) Multiple errors can be exploited to pollute "XPCNativeWrappers"
and run arbitrary script code with Chrome privileges. 

3) Multiple errors in "XSLT" and "document.loadBindingDocument()"
while creating documents can be exploited to run arbitrary script
code with Chrome privileges.

4) Multiple errors in the layout and JavaScript engines can be
exploited to corrupt memory.

5) Two errors in the image rendering implementation can be exploited
to cause a crash.

6) An error in the graphics rendering engine can be exploited to
cause a crash.

7) An error in the processing of BOM characters included in
JavaScript code can be exploited to potentially bypass script filters
and facilitate cross-site scripting attacks.

8) Multiple errors in the implementation of the "resource:" protocol
can be exploited to perform directory traversal attacks and disclose
sensitive information.

Successful exploitation of vulnerabilities #4-#6 may allow execution
of arbitrary code.

The vulnerabilities are reported in versions prior to 3.0.2.

SOLUTION:
Update to version 3.0.2.
