DESCRIPTION:
Multiple vulnerabilities have been reported in Mozilla Firefox and
Thunderbird, which can be exploited by malicious people to disclose
potentially sensitive information, conduct cross-site scripting
attacks, bypass certain security restrictions, and potentially
compromise a user's system.

1) An error when parsing invalid sequences in the Shift-JIS encoding
can be exploited to disclose potentially sensitive information and
conduct cross-site scripting attacks.

2) Some unspecified errors can be exploited to corrupt memory.

3) An error due to an unchecked allocation failure can be exploited
to corrupt memory.

4) An error when a SVG <mpath> tag links to a non-SVG element can be
exploited to corrupt memory.

5) An error when using Firebug to profile a JavaScript file with many
functions can be exploited to corrupt memory.

Successful exploitation of vulnerabilities #2 through #5 may allow
execution of arbitrary code.

6) An error within Windows D2D hardware acceleration can be exploited
to bypass the same-origin policy and read data from a different
domain.

This is related to vulnerability #7 in:
SA45581

7) An error within WebGL can be exploited to disclose random image
data from the GPU memory.

8) An error within an internal privilege check due to not respecting
the NoWaiverWrappers restrictions can be exploited to grant escalated
privileges to certain web content.

Successful exploitation of this vulnerability may allow execution of
arbitrary code.

SOLUTION:
Upgrade to version 8.0.
