Several security related problems have been discovered in Mozilla
Firefox. The Common Vulnerabilities and Exposures project identifies
the following vulnerabilities:


Web pages with extremely long titles cause subsequent launches of
the browser to appear to "hang" for up to a few minutes, or even
crash if the computer has insufficient memory. [MFSA-2006-03]


The Javascript interpreter does not properly dereference objects,
which allows remote attackers to cause a denial of service or
execute arbitrary code. [MFSA-2006-01]


The function allocation code allows attackers to cause a denial of
service and possibly execute arbitrary code. [MFSA-2006-01]


XULDocument.persist() did not validate the attribute name,
allowing an attacker to inject arbitrary XML and JavaScript code
into localstore.rdf that would be read and acted upon during
startup. [MFSA-2006-05]


An anonymous researcher for TippingPoint and the Zero Day
Initiative reported that an invalid and nonsensical ordering of
table-related tags can be exploited to execute arbitrary code.


A particular sequence of HTML tags can cause memory corruption
that can be exploited to exectute arbitary code. [MFSA-2006-18]


Georgi Guninski reported two variants of using scripts in an XBL
control to gain chrome privileges when the page is viewed under
"Print Preview".under "Print Preview". [MFSA-2006-25]


"shutdown" discovered that the crypto.generateCRMFRequest method
can be used to run arbitrary code with the privilege of the user
running the browser, which could enable an attacker to install
malware. [MFSA-2006-24]


Claus Jørgensen reported that a text input box can be pre-filled
with a filename and then turned into a file-upload control,
allowing a malicious website to steal any local file whose name
they can guess. [MFSA-2006-23]


An anonymous researcher for TippingPoint and the Zero Day
Initiative discovered an integer overflow triggered by the CSS
letter-spacing property, which could be exploited to execute
arbitrary code. [MFSA-2006-22]


"moz_bug_r_a4" discovered that some internal functions return
prototypes instead of objects, which allows remote attackers to
conduct cross-site scripting attacks. [MFSA-2006-19]


"shutdown" discovered that it is possible to bypass same-origin
protections, allowing a malicious site to inject script into
content from another site, which could allow the malicious page to
steal information such as cookies or passwords from the other
site, or perform transactions on the user's behalf if the user
were already logged in. [MFSA-2006-17]


"moz_bug_r_a4" discovered that the compilation scope of privileged
built-in XBL bindings is not fully protected from web content and
can still be executed which could be used to execute arbitrary
JavaScript, which could allow an attacker to install malware such
as viruses and password sniffers. [MFSA-2006-16]


"shutdown" discovered that it is possible to access an internal
function object which could then be used to run arbitrary
JavaScriptcode with full permissions of the user running the
browser, which could be used to install spyware or viruses.


It is possible to create JavaScript functions that would get
compiled with the wrong privileges, allowing an attacker to run
code of their choice with full permissions of the user running the
browser, which could be used to install spyware or viruses.


It is possible to trick users into downloading and saving an
executable file via an image that is overlaid by a transparent
image link that points to the executable. [MFSA-2006-13]


An integer overflow allows remote attackers to cause a denial of
service and possibly execute arbitrary bytecode via JavaScript
with a large regular expression. [MFSA-2006-11]


An unspecified vulnerability allows remote attackers to cause a
denial of service. [MFSA-2006-11]


Certain Cascading Style Sheets (CSS) can cause an out-of-bounds
array write and buffer overflow that could lead to a denial of
service and the possible execution of arbitrary code. [MFSA-2006-11]


It is possible for remote attackers to spoof secure site
indicators such as the locked icon by opening the trusted site in
a popup window, then changing the location to a malicious site.


"shutdown" discovered that it is possible to inject arbitrary
JavaScript code into a page on another site using a modal alert to
suspend an event handler while a new page is being loaded. This
could be used to steal confidential information. [MFSA-2006-09]


Igor Bukanov discovered that the JavaScript engine does not
properly handle temporary variables, which might allow remote
attackers to trigger operations on freed memory and cause memory
corruption, causing memory corruption. [MFSA-2006-10]


A regression fix that could lead to memory corruption allows
remote attackers to cause a denial of service and possibly execute
arbitrary code. [MFSA-2006-11]

For the stable distribution (sarge) these problems have been fixed in
version 1.0.4-2sarge6.

For the unstable distribution (sid) these problems have been fixed in
version 1.5.dfsg+

We recommend that you upgrade your Mozilla Firefox packages.

Upgrade Instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
