iDefense has sent us the attached draft advisory.
A 1st look at the code confirms the problem.
Patch is pretty straightforward. I'll write it and attach it there shortly.
Probably not a blocker for the relase (but if other things are postponing it to after next week, it can probably make it).

Hmm I realized at some point that the condition is not the same in the else clause, but I forgot to re-generate the patch before uploading it.
