Gentoo Linux Security Advisory

Title: Courier Authentication Library: SQL injection vulnerability (GLSA 200809-05)
Severity: normal
Exploitable: remote
Date: September 05, 2008
Bug(s): #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: net-libs/courier-authlib
Vulnerable: < 0.60.6
Unaffected: >= 0.60.6
Architectures: All supported architectures


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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/courier-authlib-0.60.6"
