medium Nessus Plugin ID 94465

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3116-1 advisory.

 It was discovered that DBus incorrectly validated the source of ActivationFailure signals. A local attacker could use this issue to cause a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-0245)

 It was discovered that DBus incorrectly handled certain format strings. A local attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. This issue is only exposed to unprivileged users when the fix for CVE-2015-0245 is not applied, hence this issue is only likely to affect Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Ubuntu 16.04 LTS and Ubuntu 16.10 have been updated as a preventative measure in the event that a new attack vector for this issue is discovered. (No CVE number)

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.
