Re: CVE request for vulnerability in OpenStack Swift

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Versions: up to 2.1.0

a vulnerability in Swift enforcement of metadata contraints. By adding
metadata in several separate calls, an authenticated attacker can
bypass the max_meta_count constraint, potentially resulting in the
storage of more metadata than allowed in configuration.

https://launchpad.net/bugs/1365350

If we pass more than 90 metadata in one request, it fails. But if we
pass 50 in one request and 50 in another request, the request is
successfully processed which is against documentation.

The above case occurs in account and container only. While in object
case, the metadata is overwritten with new request's metadata.

Use CVE-2014-7960.
