Ubuntu Security Notice USN-1494-1
July 02, 2012

linux-ti-omap4 vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

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

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

Details:

A flaw was discovered in the Linux kernel's NFSv4 (Network file system)
handling of ACLs (access control lists). A remote NFS server (attacker)
could cause a denial of service (OOPS).

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1415-omap4 3.2.0-1415.20

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-1495-1
July 02, 2012

libreoffice, libreoffice-l10n vulnerabilities
==========================================================================

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

- Ubuntu 11.10
- Ubuntu 11.04

Summary:

LibreOffice could be made to crash or potentially run programs as your
login if it opened a specially crafted file.

Software Description:
- libreoffice: Office productivity suite
- libreoffice-l10n: Office productivity suite help

Details:

Integer overflows were discovered in the graphics loading code of several
different image types. If a user were tricked into opening a specially
crafted file, an attacker could cause LibreOffice to crash or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2012-1149)

Sven Jacobi discovered an integer overflow when processing Escher graphics
records. If a user were tricked into opening a specially crafted PowerPoint
file, an attacker could cause LibreOffice to crash or possibly execute
arbitrary code with the privileges of the user invoking the program.
(CVE-2012-2334)

Update instructions:

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

Ubuntu 11.10:
libreoffice-core 1:3.4.4-0ubuntu1.2
libreoffice-l10n-common 1:3.4.4-0ubuntu1.2

Ubuntu 11.04:
libreoffice-core 1:3.3.4-0ubuntu1.2
libreoffice-l10n-common 1:3.3.3-1ubuntu1.2

After a standard system update you need to restart LibreOffice to make all
the necessary changes.

openoffice.org vulnerabilities
==========================================================================

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

- Ubuntu 10.04 LTS

Summary:

OpenOffice.org could be made to crash or potentially run programs as your
login if it opened a specially crafted file.

Software Description:
- openoffice.org: Office productivity suite

Details:

filter in OpenOffice.org. The default compiler options for affected
releases should reduce the vulnerability to a denial of service.
(CVE-2011-2685)

Huzaifa Sidhpurwala discovered that OpenOffice.org could be made to crash
if it opened a specially crafted Word document. (CVE-2011-2713)

Integer overflows were discovered in the graphics loading code of several
different image types. If a user were tricked into opening a specially
crafted file, an attacker could cause OpenOffice.org to crash or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2012-1149)
