Ubuntu Security Notice USN-1554-1
September 05, 2012
linux vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
Summary:
The system could be made to crash under certain conditions.
Software Description:
- linux: Linux kernel
Details:
A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
linux-image-3.0.0-25-generic 3.0.0-25.41
linux-image-3.0.0-25-generic-pae 3.0.0-25.41
linux-image-3.0.0-25-omap 3.0.0-25.41
linux-image-3.0.0-25-powerpc 3.0.0-25.41
linux-image-3.0.0-25-powerpc-smp 3.0.0-25.41
linux-image-3.0.0-25-powerpc64-smp 3.0.0-25.41
linux-image-3.0.0-25-server 3.0.0-25.41
linux-image-3.0.0-25-virtual 3.0.0-25.41
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.

==========================================================================
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:
Chen Haogang discovered an integer overflow that could result in memory
corruption. A local unprivileged user could use this to crash the system.
(CVE-2012-0044)
A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2372)
Some errors where discovered in the Linux kernel's UDF file system, which
is used to mount some CD-ROMs and DVDs. An unprivileged local user could
use these flaws to crash the system. (CVE-2012-3400)
Update instructions:
The problem can be corrected by updating your system to the following

Ubuntu Security Notice USN-1558-1
September 07, 2012
linux-ti-omap4 vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
Summary:
The system could be made to crash under certain conditions.
Software Description:
- linux-ti-omap4: Linux kernel for OMAP4
Details:
A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
linux-image-3.0.0-1215-omap4 3.0.0-1215.27
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.

Ubuntu Security Notice USN-1560-1
September 10, 2012
python-django vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
Summary:
Applications using Django could be made to crash or expose sensitive
information.
Software Description:
- python-django: High-level Python web development framework
Details:
It was discovered that Django incorrectly validated the scheme of a
redirect target. If a user were tricked into opening a specially crafted
URL, an attacker could possibly exploit this to conduct cross-site
scripting (XSS) attacks. (CVE-2012-3442)
It was discovered that Django incorrectly handled validating certain
images. A remote attacker could use this flaw to cause the server to
consume memory, leading to a denial of service. (CVE-2012-3443)
Jeroen Dekkers discovered that Django incorrectly handled certain image
dimensions. A remote attacker could use this flaw to cause the server to
consume resources, leading to a denial of service. (CVE-2012-3444)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
python-django 1.3.1-4ubuntu1.2
Ubuntu 11.10:
python-django 1.3-2ubuntu1.3
Ubuntu 11.04:
python-django 1.2.5-1ubuntu1.2
Ubuntu 10.04 LTS:
python-django 1.1.1-2ubuntu1.5
In general, a standard system update will make all the necessary changes.
