Ubuntu Security Notice USN-3342-1

Ubuntu Security Notice USN-3342-1
Posted Jun 29, 2017
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3342-1 - USN 3326-1 fixed a vulnerability in the Linux kernel. However, that fix introduced regressions for some Java applications. This update addresses the issue. 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. 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. Various other issues were also addressed.

linux, linux-raspi2 vulnerabilities
==========================================================================

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

- Ubuntu 16.10

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-raspi2: Linux kernel for Raspberry Pi 2

Details:

USN 3326-1 fixed a vulnerability in the Linux kernel. However, that
fix introduced regressions for some Java applications. This update
addresses the issue. We apologize for the inconvenience.

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)

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)

Li Qiang discovered that an integer overflow vulnerability existed in the
Direct Rendering Manager (DRM) driver for VMWare devices in the Linux
kernel. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2017-7294)

It was discovered that a double-free vulnerability existed 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 in the Linux kernel was performing
its 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 versions:

Ubuntu 16.10:
linux-image-4.8.0-1042-raspi2 4.8.0-1042.46
linux-image-4.8.0-58-generic 4.8.0-58.63
linux-image-4.8.0-58-generic-lpae 4.8.0-58.63
linux-image-4.8.0-58-lowlatency 4.8.0-58.63
linux-image-4.8.0-58-powerpc-e500mc 4.8.0-58.63
linux-image-4.8.0-58-powerpc-smp 4.8.0-58.63
linux-image-4.8.0-58-powerpc64-emb 4.8.0-58.63
linux-image-generic 4.8.0.58.71
linux-image-generic-lpae 4.8.0.58.71
linux-image-lowlatency 4.8.0.58.71
linux-image-powerpc-e500mc 4.8.0.58.71
linux-image-powerpc-smp 4.8.0.58.71
linux-image-powerpc64-emb 4.8.0.58.71
linux-image-powerpc64-smp 4.8.0.58.71
linux-image-raspi2 4.8.0.1042.46
linux-image-virtual 4.8.0.58.71

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.
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.
