(CVE-2015-7613)
Linux kernels built with the name spaces support(CONFIG_NAMESPACE) is vulnerable to a potential privilege escalation flaw. It could occur when a process within a container escapes the intended bind mounts to access the full file system. A privileged user inside a container could use this flaw to potentially gain full privileges on a system. (CVE-2015-2925)
A NULL-pointer dereference vulnerability was found in the Linux kernel's TCP stack, in net/netfilter/nf_nat_redirect.c in the nf_nat_redirect_ipv4() function. A remote, unauthenticated user could exploit this flaw to create a system crash (denial of service). (CVE-2015-8787)");
