I see: the kernel now treats things in /tmp (with sticky bit
permissions) differently from other places (without "weird"
permissions). Thanks for pointing this out for me!
(I never noticed this change...)

Then I agree that this issue is not exploitable in default Debian,
no need for DSA. (Sorry about the noise.)
