OSSA-2015-021: Nova network security group changes are not applied to running instances¶
October 06, 2015
Nova: <=2014.2.3, >=2015.1.0, <=2015.1.1
Sreekumar S. and Suntao independently reported a vulnerability in Nova network. Security group changes silently fail to be applied to already running instances, potentially resulting in instances not being protected by the security group. All Nova network setups are affected.
Sreekumar S. (CVE-2015-7713)
This fix will be included in future 2014.2.4 (juno) and 2015.1.2 (kilo) releases.
