glance vulnerability
==========================================================================

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Glance could be made to delete arbitrary images.

Software Description:
- glance: OpenStack Image Registry and Delivery Service

Details:

Gabe Westmaas discovered that Glance did not always properly enforce access
controls when deleting images. An authenticated user could delete arbitrary
images by using the v1 API under certain circumstances.

Update instructions:

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

Ubuntu 12.10:
python-glance 2012.2-0ubuntu2.2

Ubuntu 12.04 LTS:
python-glance 2012.1.3+stable~20120821-120fcf-0ubuntu1.2

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

apache2 vulnerabilities
==========================================================================

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Several security issues were fixed in the Apache HTTP server.

Software Description:
- apache2: Apache HTTP server

Details:

It was discovered that the mod_negotiation module incorrectly handled
certain filenames, which could result in browsers becoming vulnerable to
cross-site scripting attacks when processing the output. With cross-site
scripting vulnerabilities, if a user were tricked into viewing server
output during a crafted server request, a remote attacker could exploit
this to modify the contents, or steal confidential data (such as
passwords), within the same domain. (CVE-2012-2687)

It was discovered that the Apache HTTP Server was vulnerable to the "CRIME"
SSL data compression attack. Although this issue had been mitigated on the
client with newer web browsers, this update also disables SSL data
compression on the server. A new SSLCompression directive for Apache has
been backported that may be used to re-enable SSL data compression in
certain environments. For more information, please refer to:
http://httpd.apache.org/docs/2.4/mod/mod_ssl.html#sslcompression
(CVE-2012-4929)

Update instructions:

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

Ubuntu 12.10:
apache2.2-common 2.2.22-6ubuntu2.1

Ubuntu 12.04 LTS:
apache2.2-common 2.2.22-1ubuntu1.2

Ubuntu 11.10:
apache2.2-common 2.2.20-1ubuntu1.3

Ubuntu 10.04 LTS:
apache2.2-common 2.2.14-5ubuntu8.10

Ubuntu 8.04 LTS:
apache2.2-common 2.2.8-1ubuntu0.24

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

Ubuntu Security Notice USN-1628-1
November 08, 2012

qt4-x11 vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

Qt applications could be made to expose sensitive information over
the network.

Software Description:
- qt4-x11: Qt 4 libraries

Details:

Juliano Rizzo and Thai Duong discovered a flaw in the Transport Layer
Security (TLS) protocol when it is used with data compression. If an
attacker were able to perform a man-in-the-middle attack, this flaw
could be exploited to view sensitive information. This update disables
TLS data compression in Qt by default.

Update instructions:

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

Ubuntu 12.04 LTS:
libqt4-network 4:4.8.1-0ubuntu4.3

Ubuntu 11.10:
libqt4-network 4:4.7.4-0ubuntu8.2

Ubuntu 10.04 LTS:
libqt4-network 4:4.6.2-0ubuntu5.5

After a standard system update you need to restart any KDE sessions or
applications linked against Qt to make all the necessary changes.
