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

This update fixes the following security issues :

  - An integer overflow flaw was found in the     i915_gem_do_execbuffer() function in the Intel i915     driver in the Linux kernel. A local, unprivileged user     could use this flaw to cause a denial of service. This     issue only affected 32-bit systems. (CVE-2012-2384,     Moderate)

  - A memory leak flaw was found in the way the Linux     kernel's memory subsystem handled resource clean up in     the mmap() failure path when the MAP_HUGETLB flag was     set. A local, unprivileged user could use this flaw to     cause a denial of service. (CVE-2012-2390, Moderate)

  - A race condition was found in the way access to     inet->opt ip_options was synchronized in the Linux     kernel's TCP/IP protocol suite implementation. Depending     on the network facing applications running on the     system, a remote attacker could possibly trigger this     flaw to cause a denial of service. A local, unprivileged     user could use this flaw to cause a denial of service     regardless of the applications the system runs.
    (CVE-2012-3552, Moderate)

  - A flaw was found in the way the Linux kernel's dl2k     driver, used by certain D-Link Gigabit Ethernet     adapters, restricted IOCTLs. A local, unprivileged user     could use this flaw to issue potentially harmful IOCTLs,     which could cause Ethernet adapters using the dl2k     driver to malfunction (for example, losing network     connectivity). (CVE-2012-2313, 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)

This update also fixes several bugs.

Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted.
The system must be rebooted for this update to take effect.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-1304 advisory.

  - The rio_ioctl function in drivers/net/ethernet/dlink/dl2k.c in the Linux kernel before 3.3.7 does not     restrict access to the SIOCSMIIREG command, which allows local users to write data to an Ethernet adapter     via an ioctl call. (CVE-2012-2313)

  - Integer overflow in the i915_gem_do_execbuffer function in drivers/gpu/drm/i915/i915_gem_execbuffer.c in     the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 3.3.5 on 32-bit platforms allows     local users to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact     via a crafted ioctl call. (CVE-2012-2384)

  - Memory leak in mm/hugetlb.c in the Linux kernel before 3.4.2 allows local users to cause a denial of     service (memory consumption or system crash) via invalid MAP_HUGETLB mmap operations. (CVE-2012-2390)

  - The rds_recvmsg function in net/rds/recv.c in the Linux kernel before 3.0.44 does not initialize a certain     structure member, which allows local users to obtain potentially sensitive information from kernel stack     memory via a (1) recvfrom or (2) recvmsg system call on an RDS socket. (CVE-2012-3430)

  - Race condition in the IP implementation in the Linux kernel before 3.0 might allow remote attackers to     cause a denial of service (slab corruption and system crash) by sending packets to an application that     sets socket options during the handling of network traffic. (CVE-2012-3552)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Description of changes:

* Avoid bug caused by corrupted Ext4 filesystem.

When mounting an ext4 filesystem, the kernel was not checking for zero length extents. This would cause a BUG_ON assertion failure in the log.


* NULL pointer dereference in the SCSI subsystem.

A NULL dereference may occur if a SCSI device is physically removed without being logically removed from the system.

This would lead to a NULL dereference since the revalidation routine assumed the device is always present while it runs.


* Resource leak in USB networking driver.

The usbnet core incorrectly cleared a pointer to the underlying device resulting in a resource leak when unlinking requests.


* Inode corruption in XFS inode lookup.

The XFS inode cache did not correctly initialize the inode before insertion into the cache which could result in corruption when racing with an inode lookup.


* Kernel crash in SUNRPC cache management.

Many SUNRPC cache implementations would not handle a zero-length string resulting in a kernel panic.


* Unbalanced locking in VFS non-local alias search.

A code path responsible for finding aliases on a non-local filesystem did not correctly release a lock resulting in a system hang.


* Memory corruption on nfsd shutdown.

A race condition between closing down a SUNRPC transport and enqueueing data could result in a use-after-free condition resulting in a denial-of-service or privilege escalation.


* NULL pointer dereference with misconfigured USB FTDI devices.

A USB FTDI without a manufacturer string would result in a NULL pointer dereference and kernel crash when the device was plugged in.


* Kernel information leak in X86 ptrace TLS regset.

The TLS lookup could run off the end of the descriptor list reading from kernel memory.


* Divide-by-zero in NTP.

Integer overflow in NTP when setting the time could result in a divide-by-zero and kernel panic.


* CVE-2011-4127: KVM privilege escalation through insufficient validation in SG_IO ioctl.

Using the SG_IO IOCTL to issue SCSI requests to partitions or LVM volumes resulted in the requests being passed to the underlying block device. If a privileged user only had access to a single partition or LVM volume, they could use this flaw to bypass those restrictions and gain read and write access (and be able to issue other SCSI commands) to the entire block device.

In KVM (Kernel-based Virtual Machine) environments using raw format virtio disks backed by a partition or LVM volume, a privileged guest user could bypass intended restrictions and issue read and write requests (and other SCSI commands) on the host, and possibly access the data of other guests that reside on the same underlying block device.


* CVE-2012-2384: Integer overflow in Intel i915 command processing.

An integer overflow in the Intel i915 family display driver could cause memory corruption on 32-bit systems.


* Correctly merge virtual memory areas when binding.

When mbind() is called for adjacent areas, they are expected to be merged into a single virtual memory area.


* Small UDP packets dropped on transmission consistently in vmxnet3.

Small (<54 byte) packets will get dropped consistently on transmission due to an error in the optimization of the code.


* CVE-2011-4131: Kernel crash in NFSv4.

nfs4_getfacl decoding causes a kernel crash when a server returns more than 2 GETATTR bitmap words in response to the FATTR4_ACL attribute request.

The remote CentOS system is missing a security update which has been documented in Red Hat advisory RHSA-2012-1304.
