sendmail erratum, June 6, 2014

Please note that we're having an issue with cvsync and some of the
mirrors at this time, so cvs up -rOPENBSD_5_5 may not be a reliable
way to update. Sorry about that. Please use the patches on ftp.

OpenBSD 5.4 is also affected.

OpenBSD 5.5 errata 7, June 6, 2014: Sendmail was not properly closing file
descriptions before executing programs. This could enable local users to
interfere with an open SMTP connection.

Apply patch using:

    signify -Vep /etc/signify/openbsd-55-base.pub -x 007_sendmail.patch.sig \
	-m - | (cd /usr/src && patch -p0)

And then rebuild and install sendmail:
	cd gnu/usr.sbin/sendmail
	make obj
	make depend
	make
	make install
