Hi Michael,
I've done some digging and the good news is this issue seems to have
already been fixed upstream in 2.28, which is sitting in the git archive
to be uploaded more or less when unstable reopens for business.
It looks like 2.26 should also potentially be patched for wheezy, as
security advice DSA-1958-1 may apply to the ltdl version being used.
I'll look into this.
Cheers,
David.
