libtasn1-6 vulnerability
==========================================================================

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

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Libtasn1 could be made to crash or run programs as your login if it opened
a specially crafted file.

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

Details:

Jakub Jirasek discovered that GnuTLS incorrectly handled certain
assignments files. If a user were tricked into processing a specially
crafted assignments file, a remote attacker could possibly execute arbirary
code.

Update instructions:

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

Ubuntu 17.04:
libtasn1-6 4.10-1ubuntu0.1

Ubuntu 16.10:
libtasn1-6 4.9-4ubuntu0.1

Ubuntu 16.04 LTS:
libtasn1-6 4.7-3ubuntu0.16.04.2

Ubuntu 14.04 LTS:
libtasn1-6 3.4-3ubuntu0.5

In general, a standard system update will make all the necessary changes.
