Ubuntu Security Notice USN-1405-1
March 27, 2012
linux 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: Linux kernel
Details:
Somnath Kotur discovered an error in the Linux kernel's VLAN (virtual lan)
and be2net drivers. An attacker on the local network could exploit this
flaw to cause a denial of service. (CVE-2011-3347)
Paolo Bonzini discovered a flaw in Linux's handling of the SG_IO ioctl
command. A local user, or user in a VM could exploit this flaw to bypass
restrictions and gain read/write access to all data on the affected block
device. (CVE-2011-4127)
Sasha Levin discovered a flaw in the permission checking for device
assignments requested via the kvm ioctl in the Linux kernel. A local user
could use this flaw to crash the system causing a denial of service.
(CVE-2011-4347)
Stephan B??rwolf discovered a flaw in the KVM (kernel-based virtual
machine) subsystem of the Linux kernel. A local unprivileged user can crash
use this flaw to crash VMs causing a deny of service. (CVE-2012-0045)
A flaw was discovered in the Linux kernel's cifs file system. An
unprivileged local user could exploit this flaw to crash the system leading
to a denial of service. (CVE-2012-1090)
H. Peter Anvin reported a flaw in the Linux kernel that could crash the
system. A local user could exploit this flaw to crash the system.
(CVE-2012-1097)
A flaw was discovered in the Linux kernel's cgroups subset. A local
attacker could use this flaw to crash the system. (CVE-2012-1146)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
linux-image-3.0.0-16-generic 3.0.0-16.29
linux-image-3.0.0-16-generic-pae 3.0.0-16.29
linux-image-3.0.0-16-omap 3.0.0-16.29
linux-image-3.0.0-16-powerpc 3.0.0-16.29
linux-image-3.0.0-16-powerpc-smp 3.0.0-16.29
linux-image-3.0.0-16-powerpc64-smp 3.0.0-16.29
linux-image-3.0.0-16-server 3.0.0-16.29
linux-image-3.0.0-16-virtual 3.0.0-16.29
After a standard system update you need to reboot your computer to make
all the necessary changes.

==========================================================================
Ubuntu Security Notice USN-1410-1
March 27, 2012
linux-ec2 vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary:
The system could be made to crash under certain conditions.
Software Description:
- linux-ec2: Linux kernel for EC2
Details:
Louis Rilling discovered a flaw in Linux kernel's clone command when
CLONE_IO is specified. An unprivileged local user could exploit this to
cause a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 10.04 LTS:
linux-image-2.6.32-344-ec2 2.6.32-344.46
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.
