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.
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.
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.
Multiple buffer overflows in Firebird 1.5, one of which affects WNET, have unknown impact and attack vectors. NOTE: this issue might overlap CVE-2006-1240.
