The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412, Important)

* A use-after-free flaw was found in the xacct_add_tsk() function in the Linux kernel's taskstats subsystem. A local, unprivileged user could use this flaw to cause an information leak or a denial of service. (CVE-2012-3510, Moderate)

* A buffer overflow flaw was found in the hfs_bnode_read() function in the HFS Plus (HFS+) file system implementation in the Linux kernel. A local user able to mount a specially crafted HFS+ file system image could use this flaw to cause a denial of service or escalate their privileges. (CVE-2012-2319, Low)

* A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space.
(CVE-2012-3430, Low)

Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting CVE-2012-3412, and Alexander Peslyak for reporting CVE-2012-3510. The CVE-2012-3430 issue was discovered by the Red Hat InfiniBand team.

This update also fixes the following bugs :

* The cpuid_whitelist() function, masking the Enhanced Intel SpeedStep (EST) flag from all guests, prevented the 'cpuspeed' service from working in the privileged Xen domain (dom0). CPU scaling was therefore not possible. With this update, cpuid_whitelist() is aware whether the domain executing CPUID is privileged or not, and enables the EST flag for dom0. (BZ#846125)

* If a delayed-allocation write was performed before quota was enabled, the kernel displayed the following warning message :

WARNING: at fs/quota/dquot.c:988 dquot_claim_space+0x77/0x112()

This was because information about the delayed allocation was not recorded in the quota structure. With this update, writes prior to enabling quota are properly accounted for, and the message is not displayed. (BZ#847326)

* In Red Hat Enterprise Linux 5.9, the DSCP (Differentiated Services Code Point) netfilter module now supports mangling of the DSCP field.
(BZ#847327)

* Some subsystems clear the TIF_SIGPENDING flag during error handling in fork() paths. Previously, if the flag was cleared, the ERESTARTNOINTR error code could be returned. The underlying source code has been modified so that the error code is no longer returned.
(BZ#847359)

* An unnecessary check for the RXCW.CW bit could cause the Intel e1000e NIC (Network Interface Controller) to not work properly. The check has been removed so that the Intel e1000e NIC works as expected.
(BZ#852448)

Updated qemu-kvm packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. qemu-kvm is the user-space component for running virtual machines using KVM.

A flaw was found in the way QEMU handled VT100 terminal escape sequences when emulating certain character devices. A guest user with privileges to write to a character device that is emulated on the host using a virtual console back-end could use this flaw to crash the qemu-kvm process on the host or, possibly, escalate their privileges on the host. (CVE-2012-3515)

This flaw did not affect the default use of KVM. Affected configurations were :

* When guests were started from the command line ('/usr/libexec/qemu-kvm') without the '-nodefaults' option, and also without specifying a serial or parallel device, or a virtio-console device, that specifically does not use a virtual console (vc) back-end. (Note that Red Hat does not support invoking 'qemu-kvm' from the command line without '-nodefaults' on Red Hat Enterprise Linux 6.)

* Guests that were managed via libvirt, such as when using Virtual Machine Manager (virt-manager), but that have a serial or parallel device, or a virtio-console device, that uses a virtual console back-end. By default, guests managed via libvirt will not use a virtual console back-end for such devices.

Red Hat would like to thank the Xen project for reporting this issue.

All users of qemu-kvm should upgrade to these updated packages, which resolve this issue. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.

The xen packages contain administration tools and the xend service for managing the kernel-xen kernel for virtualization on Red Hat Enterprise Linux.

A flaw was found in the way QEMU handled VT100 terminal escape sequences when emulating certain character devices. A guest user with privileges to write to a character device that is emulated on the host using a virtual console back-end could use this flaw to crash the qemu process on the host or, possibly, escalate their privileges on the host. (CVE-2012-3515)

This flaw did not affect the default use of the Xen hypervisor implementation in Red Hat Enterprise Linux 5. This problem only affected fully-virtualized guests that have a serial or parallel device that uses a virtual console (vc) back-end. By default, the virtual console back-end is not used for such devices; only guests explicitly configured to use them in this way were affected.

Red Hat would like to thank the Xen project for reporting this issue.

All users of xen are advised to upgrade to these updated packages, which correct this issue. After installing the updated packages, all fully-virtualized guests must be restarted for this update to take effect.
