Ubuntu Security Notice USN-1577-1
September 21, 2012

linux-ti-omap4 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

A flaw was discovered in the Linux kernel's KVM (kernel virtual machine).
An administrative user in the guest OS could leverage this flaw to cause a
denial of service in the host OS. (CVE-2012-2121)

Ben Hutchings reported a flaw in the Linux kernel with some network drivers
that support TSO (TCP segment offload). A local or peer user could exploit
this flaw to to cause a denial of service. (CVE-2012-3412)

Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel
implementation of RDS sockets. A local unprivileged user could potentially
use this flaw to read privileged information from the kernel.
(CVE-2012-3430)

A flaw was discovered in the madvise feature of the Linux kernel's memory
subsystem. An unprivileged local use could exploit the flaw to cause a
denial of service (crash the system). (CVE-2012-3511)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
linux-image-2.6.38-1209-omap4 2.6.38-1209.26

After a standard system update you need to reboot your computer to make
all the necessary changes.

Ubuntu Security Notice USN-1578-1
September 21, 2012

linux-ti-omap4 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

Ben Hutchings reported a flaw in the Linux kernel with some network drivers
that support TSO (TCP segment offload). A local or peer user could exploit
this flaw to to cause a denial of service. (CVE-2012-3412)

Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel
implementation of RDS sockets. A local unprivileged user could potentially
use this flaw to read privileged information from the kernel.
(CVE-2012-3430)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
linux-image-3.0.0-1216-omap4 3.0.0-1216.28

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
