Ubuntu Update for Linux kernel vulnerabilities USN-1288-1

Please Install the Updated Packages.

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.

vsftpd on Ubuntu 11.04 , Ubuntu 10.10 , Ubuntu 10.04 LTS
