Ubuntu Security Notice USN-1842-1
May 29, 2013

kde4libs vulnerability
==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

KDE-Libs could be made to expose web credentials.

Software Description:
- kde4libs: KDE 4 core applications and libraries

Details:

It was discovered that KIO would sometimes display web authentication
credentials under certain error conditions. If a user were tricked into
opening a specially crafted web page, an attacker could potentially exploit
this to expose confidential information.

Update instructions:

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

Ubuntu 13.04:
libkio5 4:4.10.2-0ubuntu2.2

Ubuntu 12.10:
libkio5 4:4.9.5-0ubuntu0.2

Ubuntu 12.04 LTS:
libkio5 4:4.8.5-0ubuntu0.2

After a standard system update you need to restart any applications that
use KIO from KDE-Libs, such as Konqueror, to make all the necessary changes.

Ubuntu Security Notice USN-1843-1

gnutls26 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:

GnuTLS could be made to crash if it received specially crafted network
traffic.

Software Description:
- gnutls26: GNU TLS library

Details:

It was discovered that GnuTLS incorrectly handled certain padding bytes. A
remote attacker could use this flaw to cause an application using GnuTLS to
crash, leading to a denial of service.

Update instructions:

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

Ubuntu 13.04:
libgnutls26 2.12.23-1ubuntu1.1

Ubuntu 12.10:
libgnutls26 2.12.14-5ubuntu4.3

Ubuntu 12.04 LTS:
libgnutls26 2.12.14-5ubuntu3.4

Ubuntu 10.04 LTS:
libgnutls26 2.8.5-2ubuntu0.4

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

Ubuntu Security Notice USN-1838-1

linux-ti-omap4 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-ti-omap4: Linux kernel for OMAP4

Details:

An flaw was discovered in the Linux kernel's perf_events interface. A local
user could exploit this flaw to escalate privileges on the system.
(CVE-2013-2094)

A buffer overflow vulnerability was discovered in the Broadcom tg3 ethernet
driver for the Linux kernel. A local user could exploit this flaw to cause
a denial of service (crash the system) or potentially escalate privileges
on the system. (CVE-2013-1929)

Update instructions:

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

Ubuntu 13.04:
linux-image-3.5.0-225-omap4 3.5.0-225.36

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.
