Re: FWD: Squirrelmail XSS + SQL security bug?
I've done a squirrelmail NMU in fruitful cooperation with one of the
upstream squirrelmail maintainers, former stable release manager Thijs
Kinkhorst, who happens to also be a personal friend of mine.
I'm forwarding this conversation to him, in the hope that he can comment
on it. Since he is a Debian user himself, I'm sure he understands our
situation, but of course, I don't know how much time he'd like to
allocate for the 1.2.x branch that's in woody now -- don't count on
Meanwhile, I guess it'd be useful to have specific references to
issues... Adam, do you have them? Anyway, I'll ask Thijs about the 1.4.x
issues, and get back to it (in private if there are unsolved issues
