Subject: Google Talk cleartext credentials in process
	memory

Jaroslaw,

thanks for your post. You're right, the same issue occurs in *many*
applications. However, any vendor that is serious about security should
at least attempt to obfuscate the credentials in the process memory (IMHO).

I just published the advisory to let the public know that Google "fixed" this
problem, that's all.

However I respect your opinion and appreciate your post.
