Synopsis
========

Multiple stack-based buffer overflows were discovered in Firebird.

Background
==========

Firebird is a multi-platfrom, open source relational database.

Affected packages
=================

    -------------------------------------------------------------------
     Package          /      Vulnerable      /              Unaffected
    -------------------------------------------------------------------
  1  dev-db/firebird     < 2.0.3.12981.0-r2        >= 2.0.3.12981.0-r2

Description
===========

Adriano Lima and Ramon de Carvalho Valle reported that functions
isc_attach_database() and isc_create_database() do not perform proper
boundary checking when processing their input.

Impact
======

A remote attacker could send specially crafted requests to the Firebird
server on TCP port 3050, possibly resulting in the execution of
arbitrary code with the privileges of the user running Firebird
(usually firebird).

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Firebird users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-db/firebird-2.0.3.12981.0-r2"

==========
