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.

This vulnerability is reported in version 2.0.2. Other version may also be affected.
