Ubuntu Security Notice USN-1568-1
September 14, 2012
linux vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
Summary:
Several security issues were fixed in the kernel.
Software Description:
- linux: Linux kernel
Details:
Ben Hutchings reported a flaw in the Linux kernel with some network drivers
that support TSO (TCP segment offload). A local or peer user could exploit
this flaw to to cause a denial of service. (CVE-2012-3412)
Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel
implementation of RDS sockets. A local unprivileged user could potentially
use this flaw to read privileged information from the kernel.
(CVE-2012-3430)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
linux-image-3.0.0-26-generic 3.0.0-26.42
linux-image-3.0.0-26-generic-pae 3.0.0-26.42
linux-image-3.0.0-26-omap 3.0.0-26.42
linux-image-3.0.0-26-powerpc 3.0.0-26.42
linux-image-3.0.0-26-powerpc-smp 3.0.0-26.42
linux-image-3.0.0-26-powerpc64-smp 3.0.0-26.42
linux-image-3.0.0-26-server 3.0.0-26.42
linux-image-3.0.0-26-virtual 3.0.0-26.42
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-1569-1

php5 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
- Ubuntu 8.04 LTS
Summary:
Several security issues were fixed in PHP.
Software Description:
- php5: HTML-embedded scripting language interpreter
Details:
It was discovered that PHP incorrectly handled certain character sequences
when applying HTTP response-splitting protection. A remote attacker could
create a specially-crafted URL and inject arbitrary headers.
(CVE-2011-1398, CVE-2012-4388)
It was discovered that PHP incorrectly handled directories with a large
number of files. This could allow a remote attacker to execute arbitrary
code with the privileges of the web server, or to perform a denial of
service. (CVE-2012-2688)
It was discovered that PHP incorrectly parsed certain PDO prepared
statements. A remote attacker could use this flaw to cause PHP to crash,
leading to a denial of service. (CVE-2012-3450)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
php5 5.3.10-1ubuntu3.4
Ubuntu 11.10:
php5 5.3.6-13ubuntu3.9
Ubuntu 11.04:
php5 5.3.5-1ubuntu7.11
Ubuntu 10.04 LTS:
php5 5.3.2-1ubuntu4.18
Ubuntu 8.04 LTS:
php5 5.2.4-2ubuntu5.26
In general, a standard system update will make all the necessary changes.
