unrelated regression inotify/fanotify stopped working after upgrading.
This update fixes the problem.
We apologize for the inconvenience.
Brad Spengler discovered a flaw in the Linux kernel's uname system
call. An unprivileged user could exploit this flaw to read kernel
stack memory. (CVE-2012-0957)
Jon Howell reported a flaw in the Linux kernel's KVM
(Kernel-based virtual machine) subsystem's handling of the
XSAVE feature. On hosts, using qemu userspace, without the
XSAVE feature an unprivileged local attacker could exploit
this flaw to crash the system. (CVE-2012-4461)
Dmitry Monakhov reported a race condition flaw the Linux
ext4 filesystem that can expose stale data. An unprivileged
user could exploit this flaw to cause an information leak.
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)

illinois congestion control algorithm. A local attacker
could use this to cause a denial of service. (CVE-2012-4565)
A flaw was discovered in the Linux kernel's handling of new
hot-plugged memory. An unprivileged local user could exploit
this flaw to cause a denial of service by crashing the
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).
