Gentoo Linux Security Advisory

Title: ProFTPD: Multiple vulnerabilities (GLSA 200903-27)
Severity: normal
Exploitable: remote
Date: March 12, 2009
Bug(s): #258450
ID: 200903-27

Synopsis

Two vulnerabilities in ProFTPD might allow for SQL injection attacks.

Background

ProFTPD is an advanced and very configurable FTP server.

Affected Packages

Package: net-ftp/proftpd
Vulnerable: < 1.3.2
Unaffected: >= 1.3.2
Architectures: All supported architectures


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