CVE-2019-15753 Open this link in a new tabHow to fix?
Upgrade os-vif to version 1.15.2, 1.17.0 or higher.
Overview
os-vif is an A library for plugging and unplugging virtual interfaces in OpenStack.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to a hard-coded MAC aging time of 0, which disables MAC learning in Linuxbridge, forcing obligatory Ethernet flooding of non-local destinations. This not only impedes network performance but also allows users to potentially view the content of packets for instances belonging to other tenants sharing the same network. This issue occurs in PyRoute2.add() in internal/command/ip/linux/impl_pyroute2.py.
Note
Only deployments using the linuxbridge backend are affected.
