Ubuntu Security Notice USN-2173-1
April 26, 2014

linux vulnerabilities
==========================================================================

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

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

A flaw was discovered in the Linux kernel's handling of SCTP handshake. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-0101)

An error was discovered in the Linux kernel's DCCP protocol support. A
remote attacked could exploit this flaw to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2014-2523)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-58-386 2.6.32-58.120
linux-image-2.6.32-58-generic 2.6.32-58.120
linux-image-2.6.32-58-generic-pae 2.6.32-58.120
linux-image-2.6.32-58-ia64 2.6.32-58.120
linux-image-2.6.32-58-lpia 2.6.32-58.120
linux-image-2.6.32-58-powerpc 2.6.32-58.120
linux-image-2.6.32-58-powerpc-smp 2.6.32-58.120
linux-image-2.6.32-58-powerpc64-smp 2.6.32-58.120
linux-image-2.6.32-58-preempt 2.6.32-58.120
linux-image-2.6.32-58-server 2.6.32-58.120
linux-image-2.6.32-58-sparc64 2.6.32-58.120
linux-image-2.6.32-58-sparc64-smp 2.6.32-58.120
linux-image-2.6.32-58-versatile 2.6.32-58.120
linux-image-2.6.32-58-virtual 2.6.32-58.120

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.

linux-ec2 vulnerabilities
==========================================================================

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

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ec2: Linux kernel for EC2

Details:

A flaw was discovered in the Linux kernel's handling of SCTP handshake. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-0101)

An error was discovered in the Linux kernel's DCCP protocol support. A

(system crash) or possibly execute arbitrary code. (CVE-2014-2523)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-363-ec2 2.6.32-363.76

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

linux-lts-quantal vulnerabilities
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-lts-quantal: Linux hardware enablement kernel from Quantal

Details:

A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the
Linux kernel. A guest OS user could exploit this flaw to execute arbitrary
code on the host OS. (CVE-2014-0049)

Al Viro discovered an error in how CIFS in the Linux kernel handles
uncached write operations. An unprivileged local user could exploit this
flaw to cause a denial of service (system crash), obtain sensitive
information from kernel memory, or possibly gain privileges.
(CVE-2014-0069)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.5.0-49-generic 3.5.0-49.73~precise1

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