CVE-2017-5669 (retired)

Priority
Description
The do_shmat function in ipc/shm.c in the Linux kernel through 4.9.12 does
not restrict the address calculated by a certain rounding operation, which
allows local users to map page zero, and consequently bypass a protection
mechanism that exists for the mmap system call, by making crafted shmget
and shmat system calls in a privileged context.
Ubuntu-Description
Gareth Evans discovered that the shm IPC subsystem in the Linux kernel did
not properly restrict mapping page zero. A local privileged attacker could
use this to execute arbitrary code.
Notes
 jdstrand> android kernels (flo, goldfish, grouper, maguro, mako and manta) are
  not supported on the Ubuntu Touch 14.10 and earlier preview kernels
 jdstrand> linux-lts-saucy no longer receives official support
 jdstrand> linux-lts-quantal no longer receives official support
 tyhicks> See References for a link to the fix in the linux-next tree. As of
  2017-02-27, I don't see the fix in Linus' tree.
