AI Analysis
Technical Summary
FirebirdSQL firebird versions before 6.0.0, 5.0.4, 4.0.7, and 3.0.14 contain a NULL pointer dereference vulnerability (CWE-476) in the handling of op_slice network packets. The server passes an unprepared structure with a null pointer to the SDL_info() function, leading to a crash. This can be triggered remotely by an unauthenticated attacker sending a crafted packet to the server port. The vulnerability has been addressed in the fixed versions mentioned.
Potential Impact
Successful exploitation causes a denial of service by crashing the FirebirdSQL server, impacting availability. There is no impact on confidentiality or integrity according to the CVSS vector. No known exploits in the wild have been reported.
Mitigation Recommendations
Upgrade FirebirdSQL firebird to version 6.0.0, 5.0.4, 4.0.7, or 3.0.14 or later, where this vulnerability is fixed. Patch status is confirmed by the vendor's versioning information. No other mitigation is indicated.
