SECUNIA ADVISORY ID:
SA21301

VERIFY ADVISORY:
http://secunia.com/advisories/21301/

CRITICAL:
Moderately critical

IMPACT:
Exposure of sensitive information, DoS, System access

WHERE:
>From local network

SOFTWARE:
IBM Informix Dynamic Server 9.x
http://secunia.com/product/1510/
IBM Informix Dynamic Server 7.x
http://secunia.com/product/3367/
IBM Informix Dynamic Server 10.x
http://secunia.com/product/11204/

DESCRIPTION:
Multiple vulnerabilities have been reported in Informix Dynamic
Server, which can be exploited by malicious users to cause a DoS
(Denial of Service), gain knowledge of sensitive information, or
compromise the system.

1) A boundary error in the "DBINFO()" function can be exploited to
cause a buffer overflow.

2) A boundary error in the "LOTOFILE()" function can be exploited to
cause a buffer overflow.

3) A boundary error in the "FILETOCLOB()" function can be exploited
to cause a buffer overflow.

4) It's possible to execute arbitrary commands via the "dbimp" and
"dbexp" procedures in sysmaster.

5) A boundary error within the handling of usernames can be exploited
to cause a buffer overflow via an overly long username.

6) It's possible to execute arbitrary commands via a "SET DEBUG FILE"
statement.

7) A boundary error within the handling of "SET DEBUG FILE"
statements can be exploited to cause a buffer overflow.

8) A  boundary error in the "getname()" function can be exploited to
cause a buffer overflow.

9) It's possible to upgrade privileges via C code UDR.

10) Two unspecified errors can be exploited to cause a DoS.

11) User passwords are stored in plain text in shared memory.

12) Any user has permissions to create a database.

13) A boundary error in the "ifx_file_to_file()" function can be
exploited to cause a buffer overflow.

14) A boundary error within the handling of the "SQLIDEBUG"
environment variable can be exploited to cause a buffer overflow.

The vulnerabilities have been reported in versions 7.3, 9.4, and
10.0. Prior versions may also be affected.

SOLUTION:
Update to version 7.31.xD9, 9.40.xC8, or 10.00.xC4.
