CVE-2017-16939

Priority
Description
The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux
kernel before 4.13.11 allows local users to gain privileges or cause a
denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt
system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages.
Ubuntu-Description
Mohamed Ghannam discovered that a use-after-free vulnerability existed in
the Netlink subsystem (XFRM) in the Linux kernel. A local attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code.
Mitigation
If unprivileged user namespaces are not needed, set the
kernel.unprivileged_userns_clone sysctl to 0.
Notes
sbeattiepriority is low for linux_precise/esm, as unprivileged user
namespaces is not implemented there.
