CVE-2023-41038: Firebirdsql Firebird

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Firebirdsql Firebird: from 4.0.0, up to and including 4.0.3; version 5.0 only
