Test ID:	1.3.6.1.4.1.25623.1.0.71020
Category:	Ubuntu Local Security Checks
Title:	Ubuntu USN-1288-1 (vsftpd)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to vsftpd announced via advisory USN-1288-1. Details: 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: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: vsftpd 2.3.2-3ubuntu5.1 Ubuntu 11.04: vsftpd 2.3.2-3ubuntu4.1 Ubuntu 10.10: vsftpd 2.3.0~ pre2-4ubuntu2.3 Ubuntu 10.04 LTS: vsftpd 2.2.2-3ubuntu6.3 http://www.securityspace.com/smysecure/catid.html?in=USN-1288-1 CVSS Score: 7.8 CVSS Vector: AV:L/AC:L/Au:NR/C:N/I:N/A:C
