Releases

Packages

  • nova - OpenStack Compute cloud infrastructure

Details

It was discovered that, when defining security groups in Nova using
the EC2 or OS APIs, specifying the network protocol (e.g. ‘TCP’) in
the incorrect case would cause the security group to not be applied
correctly. An attacker could use this to bypass Nova security group
restrictions.
