Description:
Some vulnerabilities have been reported in Firebird, which can be exploited by malicious people to compromise a vulnerable system.
1) Boundary errors in the "isc_attach_database()" and "isc_create_database()" functions can be exploited to cause stack-based buffer overflows via specially crafted parameters passed to the affected functions.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities are reported in Firebird version WI-V2.0.1.12855, WI-V2.0.0.12748, LI-V2.0.1.12855, and LI-V2.0.0.12748. Other versions may also be affected.

2) A boundary error in the "process_function()" in fbserver.exe can be exploited to cause a stack-based buffer overflow by sending a specially crafted packet to port 3050/TCP.
Successful exploitation allows execution of arbitrary code.
This vulnerability is reported in version 2.0.2. Other version may also be affected.
Solution:
Update to version 2.0.3.12981.
