Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : vsftpd vulnerability (USN-1288-1)

Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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
not affected.

Solution :

Update the affected vsftpd package.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
