tag_insight = "USN-1699-1 fixed vulnerabilities in the Linux kernel. Due to an unrelated
  regression inotify/fanotify stopped working after upgrading. This update
  fixes the problem.

  We apologize for the inconvenience.
  
  Original advisory details:
  
  Jon Howell reported a flaw in the Linux kernel's KVM (Kernel-based virtual
  machine) subsystem's handling of the XSAVE CPU feature. On hosts without the
  XSAVE CPU feature, using qemu userspace, an unprivileged local attacker could
  exploit this flaw to crash the system. (CVE-2012-4461)
  
  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)";
