Описание
net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd.

Примечания
this is technically a kernel bug. however this has been workarounded specifically
for vsftpd by adding a kernel check before using this feature, see DSA-2304-1
