Ubuntu Security Notice USN-2232-1
June 05, 2014

openssl vulnerabilities
==========================================================================

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

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in OpenSSL.

Software Description:
- openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

J?ri Aedla discovered that OpenSSL incorrectly handled invalid DTLS
fragments. A remote attacker could use this issue to cause OpenSSL to
crash, resulting in a denial of service, or possibly execute arbitrary
code. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and
Ubuntu 14.04 LTS. (CVE-2014-0195)

Imre Rad discovered that OpenSSL incorrectly handled DTLS recursions. A
remote attacker could use this issue to cause OpenSSL to crash, resulting
in a denial of service. (CVE-2014-0221)

KIKUCHI Masashi discovered that OpenSSL incorrectly handled certain
handshakes. A remote attacker could use this flaw to perform a
man-in-the-middle attack and possibly decrypt and modify traffic.
(CVE-2014-0224)

Felix Gr?bert and Ivan Fratri? discovered that OpenSSL incorrectly handled
anonymous ECDH ciphersuites. A remote attacker could use this issue to
cause OpenSSL to crash, resulting in a denial of service. This issue only
affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS.
(CVE-2014-3470)

Update instructions:

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

Ubuntu 14.04 LTS:
libssl1.0.0 1.0.1f-1ubuntu2.2

Ubuntu 13.10:
libssl1.0.0 1.0.1e-3ubuntu1.4

Ubuntu 12.04 LTS:
libssl1.0.0 1.0.1-4ubuntu5.14

Ubuntu 10.04 LTS:
libssl0.9.8 0.9.8k-7ubuntu8.18

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

Ubuntu Security Notice USN-2233-1
June 05, 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:

Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges. (CVE-2014-3153)

Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP
Fragmentation Offload (UFO) processing. A remote attacker could leverage
this flaw to cause a denial of service (system crash). (CVE-2013-4387)

Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP
Fragmentation Offload (UFO). An unprivileged local user could exploit this
flaw to cause a denial of service (system crash) or possibly gain
administrative privileges. (CVE-2013-4470)

A flaw was discovered in the Linux kernel's IPC reference counting. An
unprivileged local user could exploit this flaw to cause a denial of
service (OOM system crash). (CVE-2013-4483)

halfdog reported an error in the AMD K7 and K8 platform support in the
Linux kernel. An unprivileged local user could exploit this flaw on AMD
based systems to cause a denial of service (task kill) or possibly gain
privileges via a crafted application. (CVE-2014-1438)

Sasha Levin reported a bug in the Linux kernel's virtual memory management
subsystem. An unprivileged local user could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-3122)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-61-386 2.6.32-61.124
linux-image-2.6.32-61-generic 2.6.32-61.124
linux-image-2.6.32-61-generic-pae 2.6.32-61.124
linux-image-2.6.32-61-ia64 2.6.32-61.124
linux-image-2.6.32-61-lpia 2.6.32-61.124
linux-image-2.6.32-61-powerpc 2.6.32-61.124
linux-image-2.6.32-61-powerpc-smp 2.6.32-61.124
linux-image-2.6.32-61-powerpc64-smp 2.6.32-61.124
linux-image-2.6.32-61-preempt 2.6.32-61.124
linux-image-2.6.32-61-server 2.6.32-61.124
linux-image-2.6.32-61-sparc64 2.6.32-61.124
linux-image-2.6.32-61-sparc64-smp 2.6.32-61.124
linux-image-2.6.32-61-versatile 2.6.32-61.124
linux-image-2.6.32-61-virtual 2.6.32-61.124

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.
