CVE-2014-9715

Publication date 31 December 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in the Linux kernel before 3.14.5 uses an insufficiently large data type for certain extension data, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via outbound network traffic that triggers extension loading, as demonstrated by configuring a PPTP tunnel in a NAT environment.

From the Ubuntu Security Team

Vincent Tondellier discovered an integer overflow in the Linux kernel's netfilter connection tracking accounting of loaded extensions. An attacker on the local area network (LAN) could potential exploit this flaw to cause a denial of service (system crash of targeted system).
