Ubuntu Security Notice USN-2367-1
October 02, 2014

openssl update
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

OpenSSL TLSv1.2 support has been improved.

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

Details:

For compatibility reasons, OpenSSL in Ubuntu 12.04 LTS disables TLSv1.2
by default when being used as a client. When forcing the use of TLSv1.2,
another compatibility feature (OPENSSL_MAX_TLS1_2_CIPHER_LENGTH) was used
that would truncate the cipher list. This would prevent certain ciphers
from being selected, and would prevent secure renegotiations. This update
removes the cipher list truncation workaround when forcing the use of
TLSv1.2.

Update instructions:

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

Ubuntu 12.04 LTS:
libssl1.0.0 1.0.1-4ubuntu5.18

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

Ubuntu Security Notice USN-2368-1
October 02, 2014

openvpn vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

OpenVPN could be made to expose sensitive information over the network.

Software Description:
- openvpn: virtual private network software

Details:

It was discovered that OpenVPN incorrectly handled HMAC comparisons when
running in UDP mode. If a remote attacker were able to perform a
man-in-the-middle attack, this flaw could possibly be used to perform a
plaintext recovery attack.

Update instructions:

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

Ubuntu 12.04 LTS:
openvpn 2.2.1-8ubuntu1.3

In general, a standard system update will make all the necessary changes.
