What is CVE-2023-41038?

Firebird, a widely-used relational database, is susceptible to a server crash when certain conditions are met involving the SET BIND statement. Versions 4.0.0 through 4.0.3 and 5.0 beta1 can experience stack corruption if a non-privileged user sends a command with an excessively long CHAR length. The result is an unexpected server crash, potentially disrupting services for users relying on the database. Fixes for these issues are available in versions 4.0.4.2981 and 5.0.0.117, with no documented workarounds for the vulnerability.

Affected Version(s)

firebird >= 4.0.0, < 4.0.4.2981 < 4.0.0, 4.0.4.2981

firebird >= 5.0 beta1, < 5.0.0.1176 < 5.0 beta1, 5.0.0.1176
