STIX 2.1

Description

The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel through 4.3.3 do not verify an address length, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application.
