Sources and claim methodology

  • Source referencesecurity.freebsd.org
Upstream source description

mp_SetEnddisc() copied a user-supplied PSN endpoint value without length validation, allowing a buffer overflow via the ppp(8) command interface. A local user with access to the ppp(8) command interface can crash ppp(8) or potentially execute arbitrary code as root.
