SUSE CVE-2026-27890

Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when processing CNCTspecificdata segments during authentication, the server assumes segments arrive in strictly ascending order. If segments arrive out of order, the Array class's grow...

SUSE 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...

SUSE CVE-2026-34232

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...

CVE-2026-40342

A flaw was found in Firebird, an open-source relational database management system. An authenticated user with CREATE FUNCTION privileges can exploit a path traversal vulnerability in the external engine plugin loader. This allows an attacker to use a crafted engine name to load an arbitrary shar...

CVE-2026-35215

A flaw was found in Firebird. In the sdldesc function, a division by zero vulnerability exists due to improper validation of the length of a decoded SDL descriptor from a slice packet. An unauthenticated attacker can exploit this by sending a specially crafted slice packet, leading to a server...

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-2026-28214

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...
