Ubuntu Security Notice USN-1937-1
September 05, 2013

php5 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:
- php5: HTML-embedded scripting language interpreter

Details:

It was discovered that PHP 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:
libapache2-mod-php5 5.4.9-4ubuntu2.3
php5-cgi 5.4.9-4ubuntu2.3
php5-cli 5.4.9-4ubuntu2.3

Ubuntu 12.10:
libapache2-mod-php5 5.4.6-1ubuntu1.4
php5-cgi 5.4.6-1ubuntu1.4
php5-cli 5.4.6-1ubuntu1.4

Ubuntu 12.04 LTS:
libapache2-mod-php5 5.3.10-1ubuntu3.8
php5-cgi 5.3.10-1ubuntu3.8
php5-cli 5.3.10-1ubuntu3.8

Ubuntu 10.04 LTS:
libapache2-mod-php5 5.3.2-1ubuntu4.21
libapache2-mod-php5filter 5.3.2-1ubuntu4.21
php5-cgi 5.3.2-1ubuntu4.21
php5-cli 5.3.2-1ubuntu4.21

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

Ubuntu Security Notice USN-1938-1
September 05, 2013

linux vulnerabilities
==========================================================================

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

- Ubuntu 13.04

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

Vasily Kulikov discovered a flaw in the Linux Kernel's perf tool that
allows for privilege escalation. A local could exploit this flaw to run
commands as root when using the perf tool. (CVE-2013-1060)

A flaw was discovered in the Xen subsystem of the Linux kernel when it
provides a guest OS read-only access to disks that support TRIM or SCSI
UNMAP. A privileged user in the guest OS could exploit this flaw to
destroy data on the disk. (CVE-2013-2140)

A flaw was discovered in the Linux kernel when an IPv6 socket is used to
connect to an IPv4 destination. A unprivileged local user could exploit
this flaw to cause a denial of service (system crash). (CVE-2013-2232)

An information leak was discovered in the IPSec key_socket implementation
in the Linux kernel. An local user could exploit this flaw to examine
potentially sensitive information in kernel memory. (CVE-2013-2234)

Hannes Frederic Sowa discovered a flaw in the setsockopt UDP_CORK option
in the Linux kernel's IPv6 stack. A local user could exploit this flaw to
cause a denial of service (system crash). (CVE-2013-4162)

Hannes Frederic Sowa discovered a flaw in the IPv6 subsystem of the Linux
kernel when the IPV6_MTU setsockopt option has been specified in
combination with the UDP_CORK option. A local user could exploit this flaw
to cause a denial of service (system crash). (CVE-2013-4163)

Update instructions:

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

Ubuntu 13.04:
linux-image-3.8.0-30-generic 3.8.0-30.44

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.

linux vulnerabilities
==========================================================================

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: Linux kernel

Details:

Vasily Kulikov discovered a flaw in the Linux Kernel's perf tool that
allows for privilege escalation. A local user could exploit this flaw to
run commands as root when using the perf tool.
(CVE-2013-1060)

Michael S. Tsirkin discovered a flaw in how the Linux kernel's KVM
subsystem allocates memory slots for the guest's address space. A local
user could exploit this flaw to gain system privileges or obtain sensitive
information from kernel memory. (CVE-2013-1943)

A flaw was discovered in the SCTP (stream control transfer protocol)
network protocol's handling of duplicate cookies in the Linux kernel. A
remote attacker could exploit this flaw to cause a denial of service
(system crash) on another remote user querying the SCTP connection.
(CVE-2013-2206)

Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the
Linux kernel's IPv6 stack. A local user could exploit this flaw to cause a
denial of service (system crash). (CVE-2013-4162)

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

Chanam Park reported a Null pointer flaw in the Linux kernel's Ceph client.
A remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2013-1059)

Vasily Kulikov discovered a flaw in the Linux Kernel's perf tool that
allows for privilege escalation. A local user could exploit this flaw to
run commands as root when using the perf tool. (CVE-2013-1060)

Jonathan Salwan discovered an information leak in the Linux kernel's cdrom
driver. A local user can exploit this leak to obtain sensitive information
from kernel memory if the CD-ROM drive is malfunctioning. (CVE-2013-2164)

A flaw was discovered in the Linux kernel when an IPv6 socket is used to
connect to an IPv4 destination. An unprivileged local user could exploit
this flaw to cause a denial of service (system crash). (CVE-2013-2232)

An information leak was discovered in the IPSec key_socket implementation
in the Linux kernel. An local user could exploit this flaw to examine
potentially sensitive information in kernel memory. (CVE-2013-2234)

Kees Cook discovered a format string vulnerability in the Linux kernel's
disk block layer. A local user with administrator privileges could exploit
this flaw to gain kernel privileges. (CVE-2013-2851)

Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the
Linux kernel's IPv6 stack. A local user could exploit this flaw to cause a
