Ubuntu Security Notice USN-2932-1

Posted Mar 14, 2016

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2932-1 - 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. It was discovered that the Linux kernel did not properly enforce rlimits for file descriptors sent over UNIX domain sockets. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
