Description

Emanuele Rocca discovered that ppp, a daemon implementing the Point-to-Point Protocol, was subject to a buffer overflow when communicating with a RADIUS server. This would allow unauthenticated users to cause a denial of service by crashing the daemon.

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