CVE-2015-6937: A NULL pointer dereference flaw was found in the Reliable

system DoS. A verification was missing that the underlying transport
exists when a connection was created. (bsc#953052)
CVE-2015-7990: RDS: Verify the underlying transport exists before
creating a connection, preventing possible DoS (bsc#953052).
CVE-2015-7872: Possible crash when trying to garbage collect an
uninstantiated keyring (bsc#951542).
CVE-2015-2925: The prepend_path function in fs/dcache.c in the Linux
kernel did not properly handle rename actions inside a bind mount, which
allowed local users to bypass an intended container protection mechanism
by renaming a directory, related to a "double-chroot attack (bnc#951625).
