October 15, 2015
click vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 15.04
– Ubuntu 14.04 LTS
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.
