Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : ppp vulnerability (USN-3810-1)

critical Nessus Plugin ID 118796

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3810-1 advisory.

 Ivan Gotovchits discovered that ppp incorrectly handled the EAP-TLS protocol. A remote attacker could use this issue to cause ppp to crash, resulting in a denial of service, or possibly bypass authentication.

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 ppp, ppp-dev and / or ppp-udeb packages.
