Ilja Van Sprundel reported a logic flaw in the Extensible Authentication
Protocol (EAP) packet parser in the Point-to-Point Protocol Daemon
(pppd). An unauthenticated attacker can take advantage of this flaw to
trigger a stack-based buffer overflow, leading to denial of service
(pppd daemon crash).
For the oldstable distribution (stretch), this problem has been fixed
in version 2.4.7-1+4+deb9u1.
For the stable distribution (buster), this problem has been fixed in
version 2.4.7-2+4.1+deb10u1.
We recommend that you upgrade your ppp packages.
