Original advisory details:

 A flaw was discovered in the Linux kernel's handling of script execution
 when module loading is enabled. A local attacker could exploit this flaw to
 cause a leak of kernel stack contents. (CVE-2012-4530)

 Florian Weimer discovered that hypervkvpd, which is distributed in the
 Linux kernel, was not correctly validating source addresses of netlink
 packets. An untrusted local user can cause a denial of service by causing
 hypervkvpd to exit. (CVE-2012-5532)");
