Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
It was discovered that the 2.6.35 and earlier Linux kernel 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) in applications that require a
separate namespace per connection, like vsftpd. This update adjusts
vsftpd to only use network namespaces on kernels that are known to be
Update the affected vsftpd package.
