Echo: firebird4.0: security update to 4.0.5.3140.ds6-17+deb13u1+e1

critical Tenable Cloud Security Plugin ID 477746

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and
3.0.14, the external engine plugin loader concatenates a user-supplied engine name into a filesystem path
without filtering path separators or .. components. An authenticated user with CREATE FUNCTION privileges
can use a crafted ENGINE name to load an arbitrary shared library from anywhere on the filesystem via path
traversal. The library's initialization code executes immediately during loading, before Firebird
validates the module, achieving code execution as the server's OS account. This issue has been fixed in
versions 5.0.4, 4.0.7 and 3.0.14. (CVE-2026-40342)

Solution

Update the firebird4.0 library and its related packages to version 4.0.5.3140.ds6-17+deb13u1+e1 or later.
