This update fixes the following security issues :
* A flaw was found in the way the Linux kernel's
journal_unmap_buffer() function handled buffer head states. On systems
that have an ext4 file system with a journal mounted, a local,
unprivileged user could use this flaw to cause a denial of service.
* A flaw was found in the way the KVM_CREATE_IRQCHIP ioctl was
handled. Calling this ioctl when at least one virtual CPU (VCPU)
already existed could lead to a NULL pointer dereference later when
the VCPU is scheduled to run. A local, unprivileged user on a KVM host
could use this flaw to crash the host. (CVE-2012-1601, Moderate)
This update also fixes several bugs. Documentation for these changes
will be available shortly from the Technical Notes document linked to
in the References section.

backported patches to correct these issues, and fix the bugs noted in
