Title: Buffer Overflow in Firebird
Date: May 23, 2004
Bugs: #20837
ID: 200405-18
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
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"
