| Revision Date: | 2016-07-03 | Version: | 1 | | Title: | CVE-2016-4997 on Ubuntu 16.04 LTS (xenial) - high. | | Description: | The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE setsockopt implementations in the netfilter subsystem in the Linux kernel before 4.6.3 allow local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement. Jesse Hertz and Tim Newsham discovered that the Linux netfilter implementation did not correctly perform validation when handling 32 bit compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local unprivileged attacker could use this to cause a denial of service (system crash) or execute arbitrary code with administrative privileges.
