Title:
binfmt-support doesn't honor flags: in /usr/share/binfmts/foo
Status in “binfmt-support” package in Ubuntu:
Won't Fix
Status in “qemu-linaro” package in Ubuntu:
Fix Committed
Bug description:
Binary package hint: binfmt-support
qemu-user-static ships a number of binfmt handlers under
/usr/share/binfmts which are registered in the postinst using 'update-
binfmts --import qemu-$target'. In natty, the resulting registrations
under /var/lib/binfmts (and in /proc/sys/fs/binfmt_misc) don't respect
the value of the flags: field set in the source file. As a result,
foreign-arch suid binaries can't be run under qemu because the kernel
has been told to use the suid bit from the non-setuid qemu
interpreter, instead of the one from the target binary.
Please fix update-binfmts to respect the flags: field, which I think
worked in previous versions.
