While we're here, how about telling us which versions of embedded software Avast is using.
The list in "About Avast" is useful, but not as useful as it could be. When a vulnerability is discovered, like the 7-zip recently, having version numbers in the credits list could remind us to upgrade quickly in case we get bitten.
I get your point, but I'm not sure if the version would be of any real help... or that there actually
is a version you can say the particular component is using.
The 7-Zip is quite a good example - the code has been heavily modified or redone from scratch and only a small part (basically just the LZMA decompression algorithm) is there in a form similar to the original. So you can't say it's version this and this because... it is not anymore. The component is shown in the About box because we want to give Igor Pavlov a credit, we did use his code somehow - but it certainly doesn't mean the whole 7-Zip vX.XX source is a part of Avast.
The recently published vulnerabilities are completely irrelevant here (they don't affect the 7-Zip format at all, they are connected to other file formats supported by 7-Zip program, a code which has never been part of Avast)... so even if the About box said it's based on version 9.x (I'm making the number up), there's no reason to update. So the only thing we could update (if we were asked to solve the "problem") is the number shown in the About box. Plus, the unpacking code is a part of virus definitions - which is updated daily anyway, so there isn't much you could do to help it (on the other hand, it's updated much faster than the program - so even if the program shows an old version in the About box, it can be much newer already).
Some libraries are used in multiple places (in multiple modules, or in the program and virus definitions) - and they might be in different versions.
So... what I'm saying is that in my opinion, showing some exact versions in the About box may bring more confusion than be of help.
On the other hand, I can imagine a page on our web commenting on recently discovered vulnerabilities (and their connection to Avast).
I can see our blog post about the 7-Zip issues noted that Avast was not affected, but I admit it may be somehow hidden.
