    CVE-2019-15753 (GCVE-0-2019-15753)

    Vulnerability from cvelistv5 – Published: 2019-08-28 20:33 – Updated: 2024-08-05 00:56
    VLAI
    Summary
    In OpenStack os-vif 1.15.x before 1.15.2, and 1.16.0, a hard-coded MAC aging time of 0 disables MAC learning in linuxbridge, forcing obligatory Ethernet flooding of non-local destinations, which both impedes network performance and allows users to possibly view the content of packets for instances belonging to other tenants sharing the same network. Only deployments using the linuxbridge backend are affected. This occurs in PyRoute2.add() in internal/command/ip/linux/impl_pyroute2.py.
