CVE-2011-1767

Published: 06 October 2011

net/ipv4/ip_gre.c in the Linux kernel before 2.6.34, when ip_gre is configured as a module, allows remote attackers to cause a denial of service (OOPS) by sending a packet during module loading.

From the Ubuntu security team

It was discovered that the GRE protocol incorrectly handled netns initialization. A remote attacker could send a packet while the ip_gre module was loading, and crash the system, leading to a denial of service.
