Synopsis

execution of arbitrary code.

Background

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

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

    -------------------------------------------------------------------

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

Cody Pierce from TippingPoint DVLabs has discovered a buffer overflow
when processing "connect" requests with an overly large "p_cnct_count"
value.

arbitrary code with the privileges of the user running Firebird.

Workaround
