The flaw sounds legit, however the attack surface is a bit shallow:
IIUC the image signature verifies image read from a malicious backend.
End user of Glance are not really affected since they will requests the API either an image name or UUID, which are not protected by signature mechanisms afaik.
Thus the attack scenario must involves a malicious glance backend operators.

Though since this is a flawed security mechanism, it surely warrants an CVE, but not necessarly an OSSA. What do you think ?
