DESCRIPTION

* Container escape in bind mounts.

Incorrect handling of disconnected paths could allow a user in a
container to escape from the container filesystem and access the host
filesystem.


* CVE-2015-6937: NULL pointer dereference in RDS socket creation.

Failure to check for binding to a transport could result in a NULL
pointer dereference when creating an RDS socket.  A local, unprivileged
user could use this flaw to crash the system.


* CVE-2015-7872: Denial-of-service when garbage collecting uninstantiated keyring.

A logic error in the security keyring subsystem leads to a kernel crash
when garbage collecting a un-instantiated keyring.  A local, un-privileged
user can use this flaw to cause a denial-of-service.


* CVE-2015-7613: Privilege escalation in IPC object initialization.

Incorrect initialization of IPC objects could result in memory
corruption when creating message queues or shared memory.  A local,
unprivileged user could use this flaw to escalate privileges.
