high Nessus Plugin ID 53240

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Wietse Venema and Victor Duchovni discovered and reported an issue that could lead to a potential information disclosure.

An unencrypted FTP command immediately following STARTTLS request would get buffered and processed prior to SSL/TLS handshake, resulting in potential authentication bypass in case a client certificate authentication was configured to provide user identity.

A report of similar issue that was originally discovered in Postfix MTA contains further technical details and discusses possible impact:
http://www.postfix.org/CVE-2011-0411.html

Users of pure-ftpd are advised to install this updated package which contains a fix for the issue.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected pure-ftpd package.
