This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Firebird SQL server. Authentication is not
required to exploit this vulnerability.
The specific flaw exists within the database service fbserver.exe,
which binds to TCP port 3050. When processing an overly long request, a
stack buffer can be overflowed through a vulnerable call to sprintf()
within the function process_packet(). If properly exploited, remote
control of the affected system can be attained with SYSTEM credentials.
