Gentoo Linux Security Advisory

Title: Firebird: Multiple buffer overflows (GLSA 200712-06)
Severity: normal
Exploitable: remote
Date: December 09, 2007
Bug(s): #195569
ID: 200712-06

Synopsis

Multiple stack-based buffer overflows were discovered in Firebird.

Background

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

Affected Packages

Package: dev-db/firebird
Vulnerable: < 2.0.3.12981.0-r2
Unaffected: >= 2.0.3.12981.0-r2
Architectures: All supported architectures


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