*** This bug is a security vulnerability ***

It looks like /run got mounted without noexec and the mtab write lies
about it:
$ grep -m1 /run /etc/mtab /proc/mounts
/etc/mtab:tmpfs /run tmpfs rw,noexec,nosuid,size=10%,mode=0755 0 0
/proc/mounts:tmpfs /run tmpfs rw,nosuid,relatime,size=1618980k,mode=755 0 0
For completeness, /run should _actually_ be mounted noexec, even if it's
root:root 0755.
** Affects: mountall (Ubuntu)
Importance: Undecided
Status: New
