Courier Authentication Library: SQL Injection vulnerability

Background

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

Description

It has been reported that some parameters used in SQL queries are not properly sanitized before being processed when using a non-Latin locale Postgres database.

Impact

A remote attacker could send specially crafted input to an application using the library, possibly resulting in the execution of arbitrary SQL commands.

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-0.62.2"
