Ubuntu 16.04 LTS / 18.04 LTS : ppp vulnerability (USN-4288-1)

critical Nessus Plugin ID 133950

Synopsis

The remote Ubuntu host is missing a security update.

Description

It was discovered that ppp incorrectly handled certain rhostname values. A remote attacker could use this issue to cause ppp to crash, resulting in a denial of service, or possibly execute arbitrary code.

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