CVE-2026-34232 firebird3.0

Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the xdrstatusvector() function does not handle the iscargcstring type when decoding an opresponse packet, causing a server crash when one is encountered in the status vector. An unauthenticated attacker can exploit this by sending a crafted opresponse packet to the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14.
