AFAIK its been fixed in -current, and it _will_ be in errata shortly..
in the meantime, there is a hotfix for the code itself, read the mailing

in /etc/fstab, make /tmp nosuid and noexec, then mount -u /tmp (you did
make tmp a seperate partition.. didn tyou?)

There are about a 1000 other places on a machine people can stick the
file to be executed. The actual problem is not tmp-related, the
provided exploit just happens to use /tmp.

Making /tmp nosuid and noexec will only stop the kiddo's that are too
stupid to change the exploit to work on such machines.
