"internal" here means local to koji, ie, in epel.
expat21 is in epel. I have no idea why this bug wouldn't have hit
before, as expat21 hasn't been changed in many years, but it is in epel.
I'm not sure either, but until recently (in the past month
or two), this didn't affect koji. It still does not affect
builds on el6 either via mock from a fedora host or directly
For the local el6 builds, I used fedpkg --release el6 srpm
and then yum-builddep on the srpm to install the deps.
However, Carl George filed a bug report on this last June:
In that report he noted that yum-builddep was a symlink to
dnf-utils. On the f27/f28/f29 systems I tested, yum-utils
had been installed, so perhaps that is one of the important
differences which keeps this from affecting normal epel
users and many local/mock builds?
Installing epel-release and then running yum install
expat-devel also doesn't pull in expat21. I thought this
might be because expat from base is already installed, so I
installed expat-devel-2.0 and then ran yum update
expat-devel and still don't get expat21 pulled in.
In any case, is there an audit trail that shows when (and
perhaps why) expat21 was added to the internal koji repo?
It seems like it should be removed from there if it's
manually tagged into that location.
Björn, have you had any luck on the CVE's affecting expat21
so an update dropping the expat-devel provides can be
