CVE-2026-40434

CVE-2026-40434 affects Anviz CrossChex Standard and is due to improper verification of the source of a communication channel, enabling an adjacent attacker on the same network to inject TCP packets and modify or disrupt client/server traffic. The documented impact is high (I/H, A/H) with no user ...

CVE-2026-33337

A flaw was found in Firebird, an open-source relational database management system. When processing a slice packet, the xdrdatum function fails to validate the length of a cstring, which can lead to a buffer overflow. An unauthenticated attacker can exploit this vulnerability by sending a special...

CVE-2026-28212

A flaw was found in Firebird, an open-source relational database management system. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted network packet to the server. During the processing of an opslice network packet, the server attempts to use an unprepared...

CVE-2026-28224

A flaw was found in Firebird. An unauthenticated attacker can exploit this vulnerability by sending a specific network packet to the server without prior authentication. This action triggers a null pointer dereference, causing the Firebird database server to crash. The primary consequence is a...

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...
