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.
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.
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.
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 (1) attach database and (2) create database functionality in Firebird before 2.0.2, when a filename exceeds MAX_PATH_LEN, has unknown impact and attack vectors, aka CORE-1405.
Unspecified vulnerability in the server in Firebird before 2.0.2 allows remote attackers to cause a denial of service (daemon crash) via an XNET session that makes multiple simultaneous requests to register events, aka CORE-1403.
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.
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.
The Services API in Firebird before 2.0.2 allows remote authenticated users without SYSDBA privileges to read the server log (firebird.log), aka CORE-1148.
