Synopsis
========

A buffer overflow via environmental variables in
Firebird may allow a
local user to manipulate or destroy local databases
and trojan the
Firebird binaries.

Background
==========

Firebird is an open source relational database that
runs on Linux,
Windows, and various UNIX systems.

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

-------------------------------------------------------------------
     Package          /   Vulnerable   /              
     Unaffected

-------------------------------------------------------------------
  1  dev-db/firebird         < 1.5                    
         >= 1.5

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

A buffer overflow exists in three Firebird binaries
(gds_inet_server,
gds_lock_mgr, and gds_drop) that is exploitable by
setting a large
value to the INTERBASE environment variable.

Impact
======

An attacker could control program execution, allowing
privilege
escalation to the UID of Firebird, full access to
Firebird databases,
and trojaning the Firebird binaries. An attacker could
use this to
compromise other user or root accounts.

Workaround
==========

There is no known workaround.

Resolution
==========

All users should upgrade to the latest version of
Firebird:

    # emerge sync

    # emerge -pv ">=dev-db/firebird-1.5"
    # emerge ">=dev-db/firebird-1.5"
