Ubuntu Security Notice USN-3338-1

21st June, 2017

linux vulnerabilities

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

  • Ubuntu 12.04 LTS

Summary

Several security issues were fixed in the Linux kernel.

Software description

  • linux - Linux kernel

Details

It was discovered that the stack guard page for processes in the Linux
kernel was not sufficiently large enough to prevent overlapping with the
heap. An attacker could leverage this with another vulnerability to execute
arbitrary code and gain administrative privileges (CVE-2017-1000364)

Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling 32 bit
compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local
unprivileged attacker could use this to cause a denial of service (system
crash) or execute arbitrary code with administrative privileges.
(CVE-2016-4997)

Update instructions

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

Ubuntu 12.04 LTS:

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.
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.

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.
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.

USN-3333-1: Linux kernel (HWE) vulnerabilities

Unix Server vom 20.06.2017 um 01:49 Uhr | Quelle ubuntu.com

Ubuntu Security Notice USN-3333-1

19th June, 2017

linux-hwe, linux-meta-hwe vulnerabilities

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

  • Ubuntu 16.04 LTS

Summary

Several security issues were fixed in the Linux kernel.

Software description

  • linux-hwe - Linux hardware enablement (HWE) kernel

Details

It was discovered that a use-after-free flaw existed in the filesystem
encryption subsystem in the Linux kernel. A local attacker could use this
to cause a denial of service (system crash). (CVE-2017-7374)

It was discovered that the stack guard page for processes in the Linux
kernel was not sufficiently large enough to prevent overlapping with the
heap. An attacker could leverage this with another vulnerability to execute
arbitrary code and gain administrative privileges (CVE-2017-1000364)

Roee Hay discovered that the parallel port printer driver in the Linux
kernel did not properly bounds check passed arguments. A local attacker
with write access to the kernel command line arguments could use this to
execute arbitrary code. (CVE-2017-1000363)

Ingo Molnar discovered that the VideoCore DRM driver in the Linux kernel
did not return an error after detecting certain overflows. A local attacker
could exploit this issue to cause a denial of service (OOPS).
(CVE-2017-5577)

A double free bug was discovered in the IPv4 stack of the Linux kernel. An
attacker could use this to cause a denial of service (system crash).
(CVE-2017-8890)

Andrey Konovalov discovered an IPv6 out-of-bounds read error in the Linux
kernel's IPv6 stack. A local attacker could cause a denial of service or
potentially other unspecified problems. (CVE-2017-9074)

Andrey Konovalov discovered a flaw in the handling of inheritance in the
Linux kernel's IPv6 stack. A local user could exploit this issue to cause a
denial of service or possibly other unspecified problems. (CVE-2017-9075)

It was discovered that dccp v6 in the Linux kernel mishandled inheritance.
A local attacker could exploit this issue to cause a denial of service or
potentially other unspecified problems. (CVE-2017-9076)

It was discovered that the transmission control protocol (tcp) v6 in the
Linux kernel mishandled inheritance. A local attacker could exploit this
issue to cause a denial of service or potentially other unspecified
problems. (CVE-2017-9077)

It was discovered that the IPv6 stack was doing over write consistency
check after the data was actually overwritten. A local attacker could
exploit this flaw to cause a denial of service (system crash).
(CVE-2017-9242)

Update instructions

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

Ubuntu 16.04 LTS:

Update instructions

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

Ubuntu 16.10:
linux-image-4.8.0-1040-raspi2 4.8.0-1040.44
linux-image-raspi2 4.8.0.1040.44

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.
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.
