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="
