Synopsis
========
Two vulnerabilities in ProFTPD might allow for SQL injection attacks.

Background
==========
ProFTPD is an advanced and very configurable FTP server.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-ftp/proftpd < 1.3.2 >= 1.3.2

Description
===========
The following vulnerabilities were reported:

* Percent characters in the username are not properly handled, which
introduces a single quote character during variable substitution by
mod_sql (CVE-2009-0542).

* Some invalid, encoded multibyte characters are not properly handled
in mod_sql_mysql and mod_sql_postgres when NLS support is enabled
(CVE-2009-0543).

Impact
======
A remote attacker could send specially crafted requests to the server,
possibly resulting in the execution of arbitrary SQL statements.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All ProFTPD users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.2"
