Scientific Linux Security Update : vsftpd on SL3.x i386/x86_64

high Nessus Plugin ID 60455

Language:

Synopsis

The remote Scientific Linux host is missing a security update.

Description

The version of vsftpd as shipped in Scientific 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.

Solution

Update the affected vsftpd package.
