Description

In FreeBSD before 11.0-STABLE, 11.0-RELEASE-p10, 10.3-STABLE, and 10.3-RELEASE-p19, ipfilter using "keep state" or "keep frags" options can cause a kernel panic when fed specially crafted packet fragments due to incorrect memory handling.

Solution(s)

  • freebsd-upgrade-base-10_3-release-p19
  • freebsd-upgrade-base-11_0-release-p10
