CVE-2020-8597

CVE-2020-8597 eap.c in pppd in ppp 2.4.2 through 2.4.8 has an rhostname buffer overflow in the eaprequest and eapresponse functions. If you manage to get "EAP: unauthenticated peer name" long enough, seems like my client limits it to 255, you can do Buffer Overflow. You still have to beat the Sta...

CVE-2026-58096

LcpDecodeConfig did not validate the length of received endpoint discriminator options against the minimum required by RFC 1717. Undersized options would trigger an out-of-bounds write. A malicious PPP peer can exploit CVE-2026-58095 and CVE-2026-58096 to crash ppp8 or potentially execute arbitra...

CVE-2026-58095

mpEnddisc used incorrect length calculations when formatting endpoint discriminator addresses for display, allowing a received endpoint option to overflow a global result buffer. A malicious PPP peer can crash ppp8 or potentially execute arbitrary code as root...

CVE-2026-58097

mpSetEnddisc copied a user-supplied PSN endpoint value without length validation, allowing a buffer overflow via the ppp8 command interface. A local user with access to the ppp8 command interface can crash ppp8 or potentially execute arbitrary code as root...

CVE-2026-58097 ppp(8): missing length validation in mp_SetEnddisc()

mpSetEnddisc copied a user-supplied PSN endpoint value without length validation, allowing a buffer overflow via the ppp8 command interface. A local user with access to the ppp8 command interface can crash ppp8 or potentially execute arbitrary code as root...

CVE-2026-58097

FreeBSD ppp(8) contains a buffer overflow in mp_SetEnddisc() , which copies a user-supplied PSN endpoint discriminator value without length validation. A local user in the "network" group (required to run the setuid-root ppp(8)) can exploit this via the command interface to crash ppp(8) or potent...
