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

high Tenable Self-Hosted Container Security Plugin ID 477742

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, when deserializing a slice packet, the xdr_datum() function does not validate that a cstring
 length conforms to the slice descriptor bounds, allowing a cstring longer than the allocated buffer to
 overflow it. An unauthenticated attacker can exploit this by sending a crafted packet to the server,
 potentially causing a crash or other security impact. This issue has been fixed in versions 5.0.4, 4.0.7
 and 3.0.14. (CVE-2026-33337)

Solution

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