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

High Nessus Plugin ID 118796

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ppp package.
