CentOS 3 : vsftpd (CESA-2008:0579)
high Nessus Plugin ID 33736
Synopsis
The remote CentOS host is missing a security update.Description
An updated vsftpd package that fixes a security issue is now available.This update has been rated as having moderate security impact by the Red Hat Security Response Team.
vsftpd (Very Secure File Transfer Protocol (FTP) daemon) is a secure FTP server for Linux and Unix-like systems.
The version of vsftpd as shipped in Red Hat Enterprise Linux 3 when used in combination with Pluggable Authentication Modules (PAM) had a memory leak on an invalid authentication attempt. Since vsftpd prior to version 2.0.5 allows any number of invalid attempts on the same connection this memory leak could lead to an eventual DoS.
(CVE-2008-2375)
This update mitigates this security issue by including a backported patch which terminates a session after a given number of failed log in attempts. The default number of attempts is 3 and this can be configured using the 'max_login_fails' directive.
All vsftpd users should upgrade to this updated package, which addresses this vulnerability.
