Summary:

Several security issues were fixed in Libtasn1.

Software Description:
- libtasn1-6: Library to manage ASN.1 structures

Details:

It was discovered that Libtasn1 incorrectly handled certain files.
If a user were tricked into opening a crafted file, an attacker could
possibly use this to cause a denial of service. This issue only
affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-10790)

It was discovered that Libtasn1 incorrectly handled certain inputs.
An attacker could possibly use this to cause Libtasn1 to hang,
resulting in a denial of service. This issue only affected Ubuntu 16.04
LTS and Ubuntu 17.10. (CVE-2018-6003)

Update instructions:

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

Ubuntu 17.10:
  libtasn1-6 4.12-2.1ubuntu0.1

Ubuntu 16.04 LTS:
  libtasn1-6 4.7-3ubuntu0.16.04.3

USN-3548-1: Linux kernel vulnerability


=========================================================================
Ubuntu Security Notice USN-3548-1
January 26, 2018

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

- Ubuntu 17.10

Summary:

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

Software Description:
- linux: Linux kernel

Details:

Jay Vosburgh discovered a logic error in the x86-64 syscall entry
implementation in the Linux kernel, introduced as part of the
mitigations for the Spectre vulnerability. A local attacker could use
this to cause a denial of service or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 17.10:
linux-image-4.13.0-32-generic 4.13.0-32.35
linux-image-4.13.0-32-lowlatency 4.13.0-32.35
linux-image-generic 4.13.0.32.34
linux-image-lowlatency 4.13.0.32.34

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.
