DESCRIPTION:
A security issue and multiple vulnerabilities have been reported in
Mozilla Firefox and Thunderbird, which can be exploited by malicious,
local users to disclose certain sensitive information and by malicious
people to bypass certain security restrictions, disclose certain
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 when handling a sub-frame can be exploited to bypass the
frame navigation policy and e.g. expose an "<iframe>" element via the
name attribute.

3) A use-after-free error within the "AttributeChildRemoved()" method
when removing child nodes from the "nsDOMAttribute" node can be
exploited to execute arbitrary code.

4) An error within the implementation of XPConnect security checks
when calling untrusted objects can be exploited to e.g. conduct
cross-site scripting attacks.

5) An error within the "mImageBufferSize()" method when encoding
images as "image/vnd.microsoft.icon" can be exploited to disclose
certain sensitive data within the resulting image.

6) An unspecified error when decoding Ogg Vorbis files can be
exploited to corrupt memory and execute arbitrary code.

7) An error within the handling of embedded XSLT stylesheets can be
exploited to corrupt memory and execute arbitrary code.

8) The security issue is caused due to the "Firefox Recovery
Key.html" file being saved with insecure file permissions when
exporting the Firefox Sync key and can be exploited to read the
contents of the file.

This security issue only affects Firefox on Linux and OS X systems.

SOLUTION:
Upgrade to Firefox version 10.0 or Thunderbird version 10.0.
