Well, that bug is only solved once we have CD images that are no longer
affected by this bug.  The first weekly testing images will be
available earliest in two weeks time (since I've set the testing
migration to 10 days and assuming no new RC bugs are discovered during
that period).

After that we still need to decide whether we also want to fix this for
the next point release.  If I understand the CD build process
correctly, the images for the next point release will only get the fix
if we also update syslinux in stretch.

Well, deb package can be downloaded from 
    http://ftp.debian.org/debian/pool/main/s/syslinux/isolinux_6.03+dfsg1-1_all.deb
though the link will no longer work after a newer version of syslinux
is uploaded to unstable.

Since deb is an ar-archive (containing more archives), you can extract
the file as follows on any *nix systems which have ar and tar commands:

ar p isolinux_6.03+dfsg1-1_all.deb data.tar.xz | \
    tar xJOf - ./usr/lib/ISOLINUX/isohdpfx.bin > isohdpfx.bin
