CVE-2015-8768 Click vulnerability
Title: Click vulnerability
Summary: Click could be made to allow malicious apps unintended access to the
system.
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.
Instructions: In general, a standard system update will make all the necessary changes. A
corresponding update will be provided to Ubuntu Phone users soon.
