[pkg-firebird-general] Bug#446373: CVE-2007-4992 stack based buffer overflow

[Nico Golde]

Package: firebird1.5
Severity: grave
Tags: security

Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for firebird1.5.

CVE-2007-4992[0]:
| 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.

If you fix this vulnerability please also include the CVE id
in your changelog entry.

I had a look at remote/server.cpp, the vulnerable code is
the following:
3049: TEXT msg[128];
...
3064 if (string = port-  port_user_name) {
3065     sprintf(msg,
3066         "SERVER/process_packet: connection rejected for %*.*s",
3067         string-  str_length, string-  str_length,
3068         string-  str_data);
3069     gds__log(msg, 0);

Kind regards
