CVE-2011-1768

Publication date 6 October 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The tunnels implementation in the Linux kernel before 2.6.34, when tunnel functionality 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 IP/IP protocol incorrectly handled netns initialization. A remote attacker could send a packet while the ipip module was loading, and crash the system, leading to a denial of service.
