CVE-2016-3134

Published: 9 March 2016

The netfilter subsystem in the Linux kernel through 4.5.2 does not validate certain offset fields, which allows local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call.

From the Ubuntu Security Team

Ben Hawkes discovered that the Linux netfilter implementation did not correctly perform validation when handling IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges.
