Test ID:1.3.6.1.4.1.25623.1.0.69408
Category:Fedora Local Security Checks
Title:Fedora Core 14 FEDORA-2011-3349 (pure-ftpd)
Summary:NOSUMMARY
Description:Description:
The remote host is missing an update to pure-ftpd
announced via advisory FEDORA-2011-3349.

Update Information:

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.
