Hi, As I started to work on next round of mozilla security updates, I found out that CVE-2010-1206 doesn't apply to 3.0.x and earlier, because the faulty code was introduced in 3.1b1 by https://bugzilla.mozilla.org/show_bug.cgi?id=254714 Also, the vulnerable package is not xulrunner, in this case, but iceweasel. Versions in etch and lenny are not affected. Mike
