iproute2 is a set of tools for managing Linux network routing and advanced features.
iproute2 was found to contain a use-after-free in get_netnsid_from_name in ip/ipnetns.c.
A remote attacker, able to feed iproute2 crafted data, may be able to cause a Denial of Service condition.
There is no known workaround at this time.
All iproute2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/iproute2-5.1.0"
