USN-3810-1: ppp vulnerability

6 November 2018

ppp could be made to crash or bypass authentication if it received specially crafted network traffic.



  • ppp - Point-to-Point Protocol (PPP)


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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04
Ubuntu 16.04
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
