Synopsis:	Moderate: vsftpd security update
Issue date:	2008-07-24
CVE Names:	CVE-2008-2375

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.

SL 3.0.x

vsftpd-1.2.1-3E.16.src.rpm
