A vulnerability has been discovered in Firebird, allowing for the execution of arbitrary code.

Affected Packages

dev-db/firebird on all architectures
Affected versions < 2.0.1

Background

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

Description

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

Impact

An unauthenticated remote attacker could send a specially crafted request to a vulnerable server, possibly resulting in the execution of arbitrary code with the privileges of the user running Firebird.

Workaround

Resolution

All Firebird users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-db/firebird-2.0.1"
