Rafal Wojtczuk from Bromium discovered that FreeBSD wasn’t handling correctly
uncanonical return addresses on Intel amd64 CPUs, allowing privilege escalation
to kernel for local users.
For the stable distribution (squeeze), this problem has been fixed in
version 8.1+dfsg-8+squeeze3.
For the testing distribution (wheezy), this problem has been fixed in
version 8.3-4.
For the unstable distribution (sid), this problem has been fixed in
version 8.3-4.
We recommend that you upgrade your kfreebsd-8 packages.
