CVE-2013-4270
Published: 08 November 2013
The net_ctl_permissions function in net/sysctl_net.c in the Linux kernel before 3.11.5 does not properly determine uid and gid values, which allows local users to bypass intended /proc/sys/net restrictions via a crafted application.
From the Ubuntu security team
Miroslav Vadkerti discovered a flaw in how the permissions for network sysctls are handled in the Linux kernel. An unprivileged local user could exploit this flaw to have privileged access to files in /proc/sys/net/.
