USN-4288-1: ppp vulnerability

20 February 2020

ppp could be made to crash or run programs if it received specially crafted network traffic.



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


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.

Update instructions

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

Ubuntu 19.10
Ubuntu 18.04
Ubuntu 16.04

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