CVE-2025-24975 Information

Aug 16, 2025 cve

Description

Firebird is a relational database. Prior to snapshot versions 4.0.6.3183 5.0.2.1610 and 6.0.0.609 Firebird is vulnerable if ExtConnPoolSize is not set equal to 0. If connections stored in ExtConnPool are not verified for presence and suitability of the CryptCallback interface is used when created versus what is available could result in a segfault in the server process. Encrypted databases accessed by execute statement on external may be accessed later by an attachment missing a key to that database. In a case when execute statement are chained segfault may happen. Additionally the segfault may affect unencrypted databases. This issue has been patched in snapshot versions 4.0.6.3183 5.0.2.1610 and 6.0.0.609 and point releases 4.0.6 and 5.0.2. A workaround for this issue involves setting ExtConnPoolSize equal to 0 in firebird.conf.
