Debian Security Advisory DSA-4632-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
February 22, 2020 https://www.debian.org/security/faq

Package : ppp
CVE ID : CVE-2020-8597
Debian Bug : 950618

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.

For the detailed security status of ppp please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/ppp
