FreeBSD Security Advisory - FreeBSD-SA-16:18.atkbd

Posted May 18, 2016

Authored by CTurt and the HardenedBSD team | Site security.freebsd.org

FreeBSD Security Advisory - Incorrect signedness comparison in the ioctl(2) handler allows a malicious local user to overwrite a portion of the kernel memory. A local user may crash the kernel, read a portion of kernel memory and execute arbitrary code in kernel context. The result of executing an arbitrary kernel code is privilege escalation.
