CVE-2017-6074

Published: 23 February 2017

The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel through 4.9.11 mishandles DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allows local users to obtain root privileges or cause a denial of service (double free) via an application that makes an IPV6_RECVPKTINFO setsockopt system call.

From the Ubuntu security team

Andrey Konovalov discovered a use-after-free vulnerability in the DCCP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges.

Mitigation

Blacklist the dccp ipv[46] autoloading aliases by
adding the following lines to /etc/modprobe.d/blacklist-dccp.conf:
  alias net-pf-2-proto-0-type-6 off
  alias net-pf-2-proto-33-type-6 off
  alias net-pf-10-proto-0-type-6 off
  alias net-pf-10-proto-33-type-6 off
Priority

High

CVSS 3 base score: 7.8
