TITLE:
Mozilla Firefox Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA34145

VERIFY ADVISORY:
http://secunia.com/advisories/34145/

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

1) Multiple errors in the layout and JavaScript engines can be
exploited to corrupt memory and potentially execute arbitrary code.

2) An error in the garbage collection process when handling a set of
cloned XUL DOM elements linked as a parent and child can be exploited
to access freed memory and execute arbitrary code.

3) An error can be exploited via the "nsIRDFService" interface and a
cross-domain redirect to bypass the same-origin policy and read XML
data from another domain.

4) An error in libpng when handling out-of-memory conditions can be
exploited to potentially execute arbitrary code.

For more information:
SA33970

5) An error when handling invisible control characters included in
the location bar can be exploited to spoof a trusted URL.

The vulnerabilities are reported in versions prior to 3.0.7.

SOLUTION:
Update to version 3.0.7.
