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	Architecture(s)
net-libs/courier-authlib	< 0.60.6	>= 0.60.6	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

Workaround

There is no known workaround at this time.

Resolution
