pyopenssl vulnerability
==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Fraudulent security certificates could allow sensitive information to be
exposed when accessing the Internet.

Software Description:
- pyopenssl: Python wrapper around the OpenSSL library

Details:

It was discovered that pyOpenSSL did not properly handle certificates with
NULL characters in the Subject Alternative Name field. An attacker could
exploit this to perform a man in the middle attack to view sensitive
information or alter encrypted communications.

Update instructions:

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

Ubuntu 13.04:
python-openssl 0.13-2ubuntu3.1
python3-openssl 0.13-2ubuntu3.1

Ubuntu 12.10:
python-openssl 0.13-2ubuntu1.1
python3-openssl 0.13-2ubuntu1.1

Ubuntu 12.04 LTS:
python-openssl 0.12-1ubuntu2.1

Ubuntu 10.04 LTS:
python-openssl 0.10-1ubuntu0.1

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

==========================================================================

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

Summary:

LibRaw could be made to crash if it opened a specially crafted file.

Software Description:
- libraw: raw image decoder library

Details:

It was discovered that LibRaw incorrectly handled photo files. If a user or
automated system were tricked into processing a specially crafted photo
file, applications linked against LibRaw could be made to crash, resulting
in a denial of service. (CVE-2013-1438, CVE-2013-1439)

Update instructions:

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

Ubuntu 13.04:
