========================================================================== Ubuntu Security Notice USN-3810-1 November 06, 2018
ppp vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
ppp could be made to crash or bypass authentication if it received specially crafted network traffic.
Software Description: - ppp: Point-to-Point Protocol (PPP)
Details:
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 LTS: ppp 2.4.7-2+2ubuntu1.1
Ubuntu 16.04 LTS: ppp 2.4.7-1+2ubuntu1.16.04.1
Ubuntu 14.04 LTS: ppp 2.4.5-5.1ubuntu2.3
In general, a standard system update will make all the necessary changes.
