From Canon:
 
Thank you for using Canon products.
 
The rubber of the viewfinder of some units of the Canon PowerShot SX50 HS compact digital camera may change color (turn white) after a short period of time. Customer support for this phenomenon is described below.
 
We take great pride in the quality and performance of our products. We offer our sincerest apologies to any customers who may be inconvenienced.
 
Phenomenon
The rubber section of the viewfinder of some PowerShot SX50 HS digital compact cameras produced in certain lots from September 1 through November 15, 2013 may turn white after a short period of time. We have determined after inquiry with the rubber manufacturer and internal analysis that the white substance is zinc bis (N,N’- dimethyldithiocarbamate).
 
Zinc bis is not used in the production of this product. The reason for the depositing of this material was the use of an improper rubber accelerator by the manufacturer of the rubber viewfinder. As a result the rubber section of the viewfinder may turn white due to a chemical reaction with the rubber accelerator and other substances. High temperature and high humidity may contribute to this condition. Zinc bis (N,N’- dimethyldithiocarbamate), which becomes deposited on the rubber surface, is created as a result of this chemical reaction.

Affected products
Only a small fraction of the PowerShot SX50 HS compact digital cameras – the ones containing the improper rubber accelerator – are affected by this phenomenon.
 
This phenomenon may occur in cameras of which the first and second digits from the left in the serial number are “69”, “70”, or “71” and the sixth digit of the serial number is “1”.
(Example serial numbers of cameras that may be affected: “69xxx1xxxxxx”, “70xxx1xxxxxx”, “71xxx1xxxxxx” (‘x’ can be any number))

Caution on use
The amount of zinc bis (N,N’-dimethyldithiocarbamate) deposited on the affected units is minimal. However, depending on one’s health and physical condition, in rare cases it is possible for zinc bis to cause allergic reactions, such as a rash, when it comes in contact with the skin of sensitive persons. In addition, if the eyes make contact with the substance, symptoms such as red eyes may develop.
 
As a precautionary measure, thoroughly wash your hands and rinse your eyes with water if they have come into contact with the rubber part of a viewfinder that has turned white. If any medical symptoms develop, please consult your physician immediately.
 
Support
If the camera meets the serial number criteria listed above, the product will be inspected and repaired free of charge. If you own one of the affected cameras please contact our Customer Support Center.

From Canon USA:
 
To Users of the EF40mm f/2.8 STM Interchangeable Lens for Canon Digital SLR Cameras
 
Thank you for using Canon products.
 
It has been confirmed that the autofocusing function of the EF40mm f/2.8 STM lens, which was released in June 2012, may not operate correctly.
 
The details of this phenomenon are described below.
 
Affected Product
 
EF40mm f/2.8 STM
 
Phenomenon
 
If pressure is applied to the lens barrel while the lens is mounted to the camera (pressure can be applied even while attaching the lens cap or while carrying the camera with the lens attached in a bag), the autofocusing function of the lens may stop working.
 
*This phenomenon does not occur during normal shooting.

Support
 
This information is for residents of the United States and Puerto Rico only. If you do not reside in the USA or Puerto Rico, please contact the Canon Customer Support Center in your region.
 
 
Note From the Review
 
This problem does not appear to affect all lenses - I tried to force my 40 STM to create this problem while creating the Canon EF 40mm f/2.8 STM Lens Review, but could not induce the issue.

Additional serial numbers have been added to the Canon EOS Rebel T4i Grip color advisory. You can check your serial number here.

Another Canon EOS Rebel T4i Product Advisory from Canon USA:
 
Thank you for using Canon products.
 
The front rubber grips of some units of the Canon EOS REBEL T4i Digital SLR camera (EOS 650D/EOS Kiss X6i overseas models) may change color (turn white) after a short period of time. Customer support for this phenomenon is described below.
 
Canon continuously strives to provide our customers with high quality, reliable products that can be used with confidence. We offer our sincerest apologies to any customers who may be inconvenienced.
 
Phenomenon
 
The front rubber grips of some EOS REBEL T4i units produced in certain lots during the sixteen-day period between May 31st through June 15th, 2012 may turn white after a short period of time. We have determined after inquiry with the rubber manufacturer and analysis, that the substance zinc bis (N,N’-dimethyldithiocarbamate) is what causes the rubber surface to turn white.
 
Zinc bis is not used in the production of this product. However, the quantity of rubber accelerator used in the affected production lots was slightly higher than usual. As a result the rubber grips may turn white due to a chemical reaction with the rubber accelerator and other substances. High temperature and high humidity may contribute to this condition. Zinc bis (N,N’-dimethyldithiocarbamate), which becomes deposited on the rubber surface, is created as a result of this chemical reaction.
 

 
Affected Product
 
Some EOS Rebel T4i digital SLR cameras produced from May 31 through June 15 may be affected.
 
You can use the serial number to check whether your camera is affected by this phenomenon. If the sixth digit of the serial number is "1" please follow the procedure below. If the sixth digit of the serial number is "2" or higher, your camera is not affected.
 
Procedure:
 
1) Click on the link below to enter your serial number.
 

 
2) Enter the 12-digit serial number (reference the image below) from your camera then click the Submit button
 
3) One of the following messages will appear.
· "Your camera is NOT affected" ? No further action is required
· "Your camera is affected" ? Please see the Support section below
 
Click here to enter your serial number (hint: read this instruction before opening that page)
 
Caution on Use
 
The amount of zinc bis (N,N'-dimethyldithiocarbamate) detected during our testing was minimal. While Canon has not received any reports of injury or allergic reactions, depending on one’s health and physical condition, in rare cases when this substance comes into contact with skin, allergic skin reactions* may develop. In addition, if eyes are rubbed after contact with the substance, symptoms, such as red eyes, may develop.
 
As a precautionary measure, thoroughly wash your hands with water if they have come in contact with the rubber grips that have turned white. (If any medical symptoms develop, please consult your physician immediately.)
 
*Please note that the occurrence of allergic skin reactions depend on the target substance, length of contact with the target substance, one’s health and physical conditions, and sensitivity of one’s skin structure, and not everyone will be affected by allergic symptoms.
 
Support
 
Preparations are underway to provide free repair service for affected cameras by replacement of the rubber grips. Once this repair service is available (ETA of mid July 2012), we will post an update on our web site and also notify registered users via email. Please register your EOS Rebel T4i, so that we can inform you via email when the free repair service will commence.

I have not seen anything official yet, but I am receiving multiple reports (thank you for sending them) that Canon Canada and Canon UK are suspending shipments of the new Canon EOS 5D Mark III until the "Light Leak" issue is resolved.
 
This all seems a bit crazy to me right now. My only thought is that I'm glad that I have my 5D III already.

Canon, Inc. has issued a similar Canon EOS 5D Mark III service notice (Google translation).
 
Canon, Inc. adds that a "dark environment" is likely to be:
 
1. If you have installed the body cap
 
2. If you attach the lens cap
 
I've been asked if I am going to send my 5D III in for service. My answer was probably, but mostly for resale purposes. But I will not likely send it in anytime soon.

Canon USA has issued a service notice for the Canon EOS 5D Mark III Digital SLR Camera.

This service notice is addressing a 5D III anomaly being referred to as the "light leak".
 
Finding a real world situation where the "light leak" anomaly causes a problem is not easy - I have not encountered any - even when I tried to do so. And, I'm probably using manual exposures if shooting in situations this dark.
 
Turning off the top LCD panel illumination before metering is the easy workaround (and possibly covering the top LCD if the light source is external).
