Firebird: Multiple vulnerabilities

Background

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

Description

Firebird does not properly handle certain types of XDR requests, resulting in an integer overflow (CVE-2008-0387). Furthermore, it is vulnerable to a buffer overflow when processing usernames (CVE-2008-0467).

Impact

A remote attacker could send specially crafted XDR requests or an overly long username to the vulnerable server, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Firebird users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-db/firebird-2.0.3.12981.0-r5"
