CVSS v3.1 |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the sdl_desc() function does not validate the length of a decoded SDL descriptor from a slice packet. A zero-length descriptor is later used to calculate the number of slice items, causing a division by zero. An unauthenticated attacker can exploit this by sending a crafted slice packet to crash the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the external engine plugin loader concatenates a user-supplied engine name into a filesystem path without filtering path separators or .. components. An authenticated user with CREATE FUNCTION privileges can use a crafted ENGINE name to load an arbitrary shared library from anywhere on the filesystem via path traversal. The library's initialization code executes immediately during loading, before Firebird validates the module, achieving code execution as the server's OS account. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the xdr_status_vector() function does not handle the isc_arg_cstring type when decoding an op_response packet, causing a server crash when one is encountered in the status vector. An unauthenticated attacker can exploit this by sending a crafted op_response packet to the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when deserializing a slice packet, the xdr_datum() function does not validate that a cstring length conforms to the slice descriptor bounds, allowing a cstring longer than the allocated buffer to overflow it. An unauthenticated attacker can exploit this by sending a crafted packet to the server, potentially causing a crash or other security impact. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions FB3 of the client library placed incorrect data length values into XSQLDA fields when communicating with FB4 or higher servers, resulting in an information leak. This issue is fixed by upgrading to the FB4 client or higher. |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when processing CNCT_specific_data segments during authentication, the server assumes segments arrive in strictly ascending order. If segments arrive out of order, the Array class's grow() method computes a negative size value, causing a SIGSEGV crash. An unauthenticated attacker who knows only the server's IP and port can exploit this to crash the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions prior to 6.0.0, 5.0.4, 4.0.7 and 3.0.14, when processing an op_slice network packet, the server passes an unprepared structure containing a null pointer to the SDL_info() function, resulting in a null pointer dereference and server crash. An unauthenticated attacker can trigger this by sending a crafted packet to the server port. This issue has been fixed in versions 6.0.0, 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the ClumpletReader::getClumpletSize() function can overflow the totalLength value when parsing a Wide type clumplet, causing an infinite loop. An authenticated user with INSERT privileges on any table can exploit this via a crafted Batch Parameter Block to cause a denial of service against the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, when the server receives an op_crypt_key_callback packet without prior authentication, the port_server_crypt_callback handler is not initialized, resulting in a null pointer dereference and server crash. An unauthenticated attacker who knows only the server's IP and port can exploit this to crash the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14. |
| Unspecified vulnerability in the server in Firebird before 2.0.2, when a Superserver/TCP/IP environment is configured, allows remote attackers to cause a denial of service (CPU and memory consumption) via "large network packets with garbage", aka CORE-1397. |
| Firebird 1.5 allows remote authenticated users without SYSDBA and owner permissions to overwrite a database by creating a database. |
| fb_lock_mgr in Firebird 1.5 uses weak permissions (0666) for the semaphore array, which allows local users to cause a denial of service (blocked query processing) by locking semaphores. |
| Stack-based buffer overflow in the process_packet function in fbserver.exe in Firebird SQL 2.0.2 allows remote attackers to execute arbitrary code via a long request to TCP port 3050. |
| Unspecified vulnerability in the Services API in Firebird before 2.0.2 allows remote attackers to cause a denial of service, aka CORE-1149. |
| Multiple buffer overflows in Firebird 2.1 allow attackers to trigger memory corruption and possibly have other unspecified impact via certain input processed by (1) config\ConfigFile.cpp or (2) msgs\check_msgs.epp. NOTE: if ConfigFile.cpp reads a configuration file with restrictive permissions, then the ConfigFile.cpp vector may not cross privilege boundaries and perhaps should not be included in CVE. |
| Multiple stack-based buffer overflows in Firebird LI 1.5.3.4870 and 1.5.4.4910, and WI 1.5.3.4870 and 1.5.4.4910, allow remote attackers to execute arbitrary code via (1) a long service attach request on TCP port 3050 to the SVC_attach function or (2) unspecified vectors involving the INET_connect function. |
| Stack-based buffer overflow in Firebird before 2.0.4, and 2.1.x before 2.1.0 RC1, might allow remote attackers to execute arbitrary code via a long username. |
| Buffer overflow in fbserver.exe in Firebird SQL 2 before 2.0.1 allows remote attackers to execute arbitrary code via a large p_cnct_count value in a p_cnct structure in a connect (0x01) request to port 3050/tcp, related to "an InterBase version of gds32.dll." |
| Multiple stack-based buffer overflows in Firebird LI 2.0.0.12748 and 2.0.1.12855, and WI 2.0.0.12748 and 2.0.1.12855, allow remote attackers to execute arbitrary code via (1) a long attach request on TCP port 3050 to the isc_attach_database function or (2) a long create request on TCP port 3050 to the isc_create_database function. |
| Unspecified vulnerability in the server in Firebird before 2.0.2 allows remote attackers to determine the existence of arbitrary files, and possibly obtain other "file access," via unknown vectors, aka CORE-1312. |
