=========================================================================Ubuntu Security Notice USN-
Click could be made to allow malicious apps unintended access to the system.

Summary

Click could be made to allow malicious apps unintended access to the

system.

Software Description:

- click: Click package manager

Details:

It was discovered that click did not properly perform input sanitization

during click package installation. If a user were tricked into installing a

crafted click package, a remote attacker could exploit this to escalate

privileges by tricking click into installing lenient security policy for

the installed application.

Update Instructions

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

Ubuntu 15.04:
  python3-click                   0.4.38.5ubuntu0.2

Ubuntu 14.04 LTS:
  python3-click                   0.4.21.1ubuntu0.2

In general, a standard system update will make all the necessary changes. A
corresponding update will be provided to Ubuntu Phone users soon.
