Firebirdsql: >> Firebird Security Vulnerabilities
Firebird is a relational database. Prior to versions 3.0.13, 4.0.6, and 5.0.3, there is an XDR message parsing NULL pointer dereference denial-of-service vulnerability in Firebird. This specific flaw exists within the parsing of xdr message from client. It leads to NULL pointer dereference and DoS. This issue has been patched in versions 3.0.13, 4.0.6, and 5.0.3.

Firebird is a relational database. Versions 4.0.0 through 4.0.3 and version 5.0 beta1 are vulnerable to a server crash when a user uses a specific form of SET BIND statement. Any non-privileged user with minimum access to a server may type a statement with a long `CHAR` length, which causes the server to crash due to stack corruption. Versions 4.0.4.2981 and 5.0.0.117 contain fixes for this issue. No known workarounds are available.

Integer overflow in Firebird SQL 1.0.3 and earlier, 1.5.x before 1.5.6, 2.0.x before 2.0.4, and 2.1.x before 2.1.0 RC1 might allow remote attackers to execute arbitrary code via crafted (1) op_receive, (2) op_start, (3) op_start_and_receive, (4) op_send, (5) op_start_and_send, and (6) op_start_send_and_receive XDR requests, which triggers memory corruption.
