libwmf vulnerabilities

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

• Ubuntu 15.04
• Ubuntu 14.10
• Ubuntu 14.04 LTS
• Ubuntu 12.04 LTS

Summary

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

Software description

• libwmf
  – Windows metafile conversion tools

Details

Fernando Muñoz and Stefan Cornelius discovered that libwmf incorrectly
handled certain malformed images. If a user or automated system were
tricked into opening a crafted image file, an attacker could cause a denial
of service or execute arbitrary code with privileges of the user invoking
the program.

Update instructions

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

Ubuntu 15.04:

libwmf0.2-7

0.2.8.4-10.3ubuntu1.15.04.1

Ubuntu 14.10:

libwmf0.2-7

0.2.8.4-10.3ubuntu1.14.10.1

Ubuntu 14.04 LTS:

libwmf0.2-7

0.2.8.4-10.3ubuntu1.14.04.1

Ubuntu 12.04 LTS:

libwmf0.2-7

0.2.8.4-10ubuntu1.1

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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

Ubuntu Security Notice USN-2660-1

linux vulnerability

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

• Ubuntu 12.04 LTS

Summary

The system could be made to expose sensitive information over the
local applications.

Software description

• linux
  – Linux kernel

Details

A race condition was discovered in the Linux kernel’s file_handle size
verification. A local user could exploit this flaw to read potentially
sensative memory locations.

Update instructions

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

Ubuntu 12.04 LTS:

linux-image-3.2.0-87-powerpc64-smp

3.2.0-87.125

linux-image-3.2.0-87-powerpc-smp

3.2.0-87.125

linux-image-3.2.0-87-generic-pae

3.2.0-87.125

linux-image-3.2.0-87-virtual

3.2.0-87.125

linux-image-3.2.0-87-highbank

3.2.0-87.125

linux-image-3.2.0-87-omap

3.2.0-87.125

linux-image-3.2.0-87-generic

3.2.0-87.125

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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-lts-trusty vulnerabilities

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

• Ubuntu 12.04 LTS

Summary

Several security issues were fixed in the kernel.

Software description

• linux-lts-trusty
  – Linux hardware enablement kernel from Trusty

Details

Alexandre Oliva reported a race condition flaw in the btrfs file system’s
handling of extended attributes (xattrs). A local attacker could exploit
this flaw to bypass ACLs and potentially escalate privileges.
(CVE-2014-9710)

A race condition was discovered in the Linux kernel’s file_handle size
verification. A local user could exploit this flaw to read potentially
sensative memory locations. (CVE-2015-1420)

A underflow error was discovered in the Linux kernel’s Ozmo Devices USB
over WiFi host controller driver. A remote attacker could exploit this flaw
to cause a denial of service (system crash) or potentially execute
arbitrary code via a specially crafted packet. (CVE-2015-4001)

A bounds check error was discovered in the Linux kernel’s Ozmo Devices USB
over WiFi host controller driver. A remote attacker could exploit this flaw
to cause a denial of service (system crash) or potentially execute
arbitrary code via a specially crafted packet. (CVE-2015-4002)

A division by zero error was discovered in the Linux kernel’s Ozmo Devices
USB over WiFi host controller driver. A remote attacker could exploit this
flaw to cause a denial of service (system crash). (CVE-2015-4003)

Carl H Lunde discovered missing sanity checks in the the Linux kernel’s UDF
file system (CONFIG_UDF_FS). A local attacker could exploit this flaw to
cause a denial of service (system crash) by using a corrupted file system
image. (CVE-2015-4167)

Update instructions

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

Ubuntu 12.04 LTS:

linux-image-3.13.0-57-generic-lpae

3.13.0-57.95~precise1
