VERIFY ADVISORY:
http://secunia.com/advisories/22223/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
IBM Informix Dynamic Server 10.x
http://secunia.com/product/11204/

DESCRIPTION:
Larry Cashdollar has discovered a vulnerability in IBM Informix
Dynamic Server, which can be exploited by malicious, local users to
perform certain actions with escalated privileges.

The vulnerability is caused due to the temporary file
"/tmp/installserver.txt" being created insecurely during the install
process. This can be exploited via symlink attacks to append data to
arbitrary files with privileges of the user running the installation
script.

The vulnerability has been confirmed in version 10.UC3RC1 Trial for
Linux. Other versions may also be affected.

SOLUTION:
Grant only trusted user access to affected systems.

PROVIDED AND/OR DISCOVERED BY:
