linux-lts-quantal 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-quantal: Linux hardware enablement kernel from Quantal

Details:

Sasha Levin reported a flaw in the Linux kernel's point-to-point protocol
(PPP) when used with the Layer Two Tunneling Protocol (L2TP). A local user
could exploit this flaw to gain administrative privileges. (CVE-2014-4943)

Michael S. Tsirkin discovered an information leak in the Linux kernel's
segmentation of skbs when using the zerocopy feature of vhost-net. A local
attacker could exploit this flaw to gain potentially sensitive information
from kernel memory. (CVE-2014-0131)

Salva Peir? discovered an information leak in the Linux kernel's media-
device driver. A local attacker could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2014-1739)

A flaw was discovered in the Linux kernel's audit subsystem when auditing
certain syscalls. A local attacker could exploit this flaw to obtain
potentially sensitive single-bit values from kernel memory or cause a
denial of service (OOPS). (CVE-2014-3917)

A flaw was discovered in the Linux kernel's implementation of user
namespaces with respect to inode permissions. A local user could exploit
this flaw by creating a user namespace to gain administrative privileges.
(CVE-2014-4014)

An information leak was discovered in the rd_mcp backend of the iSCSI
target subsystem in the Linux kernel. A local user could exploit this flaw
to obtain sensitive information from ramdisk_mcp memory by leveraging
access to a SCSI initiator. (CVE-2014-4027)

Don Bailey discovered a flaw in the LZO decompress algorithm used by the
Linux kernel. An attacker could exploit this flaw to cause a denial of
service (memory corruption or OOPS). (CVE-2014-4608)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.5.0-54-generic 3.5.0-54.81~precise1

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.

kernel's implementation of the LZ4 decompression algorithm, when used by
code not complying with API limitations. An attacker could exploit this
flaw to cause a denial of service (memory corruption) or possibly other
unspecified impact. (CVE-2014-4611)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.11.0-26-generic 3.11.0-26.45~precise1
linux-image-3.11.0-26-generic-lpae 3.11.0-26.45~precise1

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 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

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

Details:

Sasha Levin reported a flaw in the Linux kernel's point-to-point protocol
(PPP) when used with the Layer Two Tunneling Protocol (L2TP). A local user
could exploit this flaw to gain administrative privileges. (CVE-2014-4943)

Michael S. Tsirkin discovered an information leak in the Linux kernel's
segmentation of skbs when using the zerocopy feature of vhost-net. A local
attacker could exploit this flaw to gain potentially sensitive information
from kernel memory. (CVE-2014-0131)

Don Bailey discovered a flaw in the LZO decompress algorithm used by the
Linux kernel. An attacker could exploit this flaw to cause a denial of
service (memory corruption or OOPS). (CVE-2014-4608)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1451-omap4 3.2.0-1451.71

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.
