Ubuntu Security Notice USN-3779-1
October 02, 2018
linux vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 12.04 ESM
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
– linux: Linux kernel
Details:
It was discovered that an integer overflow vulnerability existed in the
Linux kernel when loading an executable to run. A local attacker could use
this to gain administrative privileges. (CVE-2018-14634)
It was discovered that a stack-based buffer overflow existed in the iSCSI
target implementation of the Linux kernel. A remote attacker could use this
to cause a denial of service (system crash). (CVE-2018-14633)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 ESM:
linux-image-3.2.0-136-generic 3.2.0-136.182
linux-image-3.2.0-136-generic-pae 3.2.0-136.182
linux-image-3.2.0-136-highbank 3.2.0-136.182
linux-image-3.2.0-136-omap 3.2.0-136.182
linux-image-3.2.0-136-powerpc-smp 3.2.0-136.182
linux-image-3.2.0-136-powerpc64-smp 3.2.0-136.182
linux-image-3.2.0-136-virtual 3.2.0-136.182
linux-image-generic 3.2.0.136.151
linux-image-generic-pae 3.2.0.136.151
linux-image-highbank 3.2.0.136.151
linux-image-omap 3.2.0.136.151
linux-image-powerpc 3.2.0.136.151
linux-image-powerpc-smp 3.2.0.136.151
linux-image-powerpc64-smp 3.2.0.136.151
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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
