CVE-2017-5897

Published: 23 March 2017

The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.

From the Ubuntu security team

Andrey Konovalov discovered an out-of-bounds access in the IPv6 Generic Routing Encapsulation (GRE) tunneling implementation in the Linux kernel. An attacker could use this to possibly expose sensitive information.
