USN-2731-1: Linux kernel vulnerability

Ubuntu Security Notice USN-2731-1

3rd September, 2015

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.

Software description

  • linux
    – Linux kernel

Details

Benjamin Randazzo discovered an information leak in the md (multiple
device) driver when the bitmap_info.file is disabled. A local privileged
attacker could use this to obtain sensitive information from the kernel.

Update instructions

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-90-powerpc64-smp

3.2.0-90.128
linux-image-3.2.0-90-powerpc-smp

3.2.0-90.128
linux-image-3.2.0-90-generic-pae

3.2.0-90.128
linux-image-3.2.0-90-virtual

3.2.0-90.128
linux-image-3.2.0-90-highbank

3.2.0-90.128
linux-image-3.2.0-90-omap

3.2.0-90.128
linux-image-3.2.0-90-generic

3.2.0-90.128

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-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 expose sensitive information.

Software description

  • linux-ti-omap4
    – Linux kernel for OMAP4

Details

Benjamin Randazzo discovered an information leak in the md (multiple
device) driver when the bitmap_info.file is disabled. A local privileged
attacker could use this to obtain sensitive information from the kernel.

Update instructions

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1470-omap4

3.2.0-1470.91

USN-2733-1: Linux kernel (Trusty HWE) vulnerability

Ubuntu Security Notice USN-2733-1

3rd September, 2015

linux-lts-trusty vulnerability

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

  • Ubuntu 12.04 LTS

Summary

The system could be made to crash or run programs as an administrator.

Software description

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

Details

It was discovered that an integer overflow error existed in the SCSI
generic (sg) driver in the Linux kernel. A local attacker with write
permission to a SCSI generic device could use this to cause a denial of
service (system crash) or potentially escalate their privileges.

Update instructions

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

Ubuntu 12.04 LTS:
linux-image-3.13.0-63-generic

3.13.0-63.104~precise1
linux-image-3.13.0-63-generic-lpae

CVE-2014-9605 (netsweeper)

WebUpgrade in Netsweeper before 3.1.10, 4.0.x before 4.0.9, and 4.1.x before 4.1.2 allows remote attackers to bypass authentication and create a system backup tarball, restart the server, or stop the filters on the server via a ‘ (single quote) character in the login and password parameters to webupgrade/webupgrade.php. NOTE: this was originally reported as an SQL injection vulnerability, but this may be inaccurate.
