This blog post provides details about four vulnerabilities we found in the IPv6 stack of FreeBSD, more specifically in rtsold(8), the router solicitation daemon. The bugs affected all supported versions of FreeBSD, and the most severe of them could allow an attacker attached to the same physical link to gain remote code execution as root on vulnerable systems. The vulnerabilities were discovered and reported to FreeBSD Security Team in November 2020. FreeBSD issued fixes for these bugs on December 1st, 2020 along with security advisory FreeBSD-SA-20:32.rtsold.

On September 2018, FreeBSD published the security advisory FreeBSD-SA-18:12, fixing a kernel memory disclosure vulnerability affecting all the supported versions of this operating system.
