Possible MS10-080 en MS12-030 security problems

One of our customers claims they have security problems with Excel files generated with Flexcel for .NET.

Is anyone aware of any security problems related to the Microsoft MS10-080 en MS12-030 bulletins?

Hi,

We aren't aware of any issues with this, and haven't got any report about it from any of our customers.

I would start by verifying that you are using an up-to-date FlexCel. Versions before 5.1 can show security warnings:

If FlexCel is up to date, can I get any more information on the exact errors you are getting? Maybe a file that reproduces the problem?  (You can email it to me at adrian@tmssoftware.com ) Some screenshots or anything that could give me some hint on what could be happening?

Regards,
