Detail
| 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 |
