DESCRIPTION:
Multiple vulnerabilities have been reported in Mozilla Firefox and
Thunderbird, where one has an unknown impact and others can be
exploited by malicious people to disclose sensitive information and
compromise a user's system.

1) Some unspecified errors can be exploited to corrupt memory. No
further information is currently available.

2) An error exists within the YARR regular expression library when
parsing javascript content.

3) An error within the SVG implementation when SVG elements are
removed during a DOMAttrModified event can be exploited to cause an
out-of-bounds memory access.

4) The application does not properly handle SVG animation accessKey
events when JavaScript is disabled. This can lead to the user's key
strokes being leaked.

5) An error within the plugin handler when deleting DOM frame can be
exploited to dereference memory.

NOTE: This vulnerability only affects Mac OS X.

6) An error exists within the handling of OGG <video> elements.

Successful exploitation of vulnerabilities #1 - #3 and #5 may allow
execution of arbitrary code.

SOLUTION:
Upgrade to version 9.0.
