Ubuntu 14.04 LTS : Click vulnerability (USN-2771-1)

critical Nessus Plugin ID 86415

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2771-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
