Related bugreports: #258450

Two vulnerabilities in ProFTPD might allow for SQL injection attacks.

2. Impact Information

ProFTPD is an advanced and very configurable FTP server.

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).

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

3. Resolution Information

There is no known workaround at this time.

All ProFTPD users should upgrade to the latest version:

Code Listing 3.1: Resolution

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