Severity: Normal
   Title: Courier Authentication Library: SQL injection vulnerability
    Date: September 05, 2008
    Bugs: #225407
      ID: 200809-05

Synopsis

An SQL injection vulnerability has been discovered in the Courier
Authentication Library.

Background

The Courier Authentication Library is a generic authentication API that
encapsulates the process of validating account passwords.

Affected packages

  -------------------------------------------------------------------
   Package                   /  Vulnerable  /             Unaffected
  -------------------------------------------------------------------
1  net-libs/courier-authlib      < 0.60.6                  >= 0.60.6

Description

It has been discovered that some input (e.g. the username) passed to
the library are not properly sanitised before being used in SQL
queries.

Impact

A remote attacker could provide specially crafted input to the library,
possibly resulting in the remote execution of arbitrary SQL commands.
NOTE: Exploitation of this vulnerability requires that a MySQL database
is used for authentication and that a Non-Latin character set is
selected.

Workaround

There is no known workaround at this time.

Resolution

All Courier Authentication Library users should upgrade to the latest
version:

emerge --sync

emerge --ask --oneshot --verbose ">=net-libs/courier-authlib-0.60.6"
