CVE-2026-33337

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 xdrdatum function does not validate that a cstring length conforms to the slice descriptor bounds, allowing a cstring longer than the allocated...

CVE-2026-28212

Firebird is an open-source relational database management system. In versions prior to 6.0.0, 5.0.4, 4.0.7 and 3.0.14, when processing an opslice network packet, the server passes an unprepared structure containing a null pointer to the SDLinfo function, resulting in a null pointer dereference an...

CVE-2026-28224

Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when the server receives an opcryptkeycallback packet without prior authentication, the portservercryptcallback handler is not initialized, resulting in a null pointer dereference and...

CVE-2026-28214

Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the ClumpletReader::getClumpletSize function can overflow the totalLength value when parsing a Wide type clumplet, causing an infinite loop. An authenticated user with INSERT privileges...
